Running faster without trying harder
Strength Training
Sources: The Run Smarter Podcast (Brodie Sharp), Runners World.
Increasing the efficiency of your running bio-mechanics. Strengthening the muscles that support your body in ideal alignment while running can result in more efficient use of energy. Even trained distance runners have shown improvements of up to 8% in running economy following a period of resistance training.
Core – strengthening your core will help stability, reduce asymmetry and increase balance, so reducing stress or over-exertion of individual leg muscles.
Don’t make the assumption that strength training will increase your body weight and as a result slow you down.
Nutrition 1
I’ve always been interested in food. 😁
The adult human body re-generates (totally replaces every
cell) roughly once every 7 years. The old you goes down the toilet (mostly).
Unlike plants that make their nutrition in leaves with air and sunlight, humans
need to consume food to grow, repair and provide energy. I'm so glad.
We are literally made out of food…in fact, the food that we’ve eaten in the
past 7 years. So, it seems to make sense to ensure the food we put in is the right stuff to make the body we want..
There’s always a lot of talk about the energy side of food –
carbos and fats.
In this post/blog I want to talk about the other major food group:
Protein
If you have a lack of it, you will lose muscle mass – this cuts strength, slows metabolism, can cause anemia, weakness and fatigue. Too little protein leads to lethargy; hair, nails and skin issues, increased risk of stress fractures, risk of infections, mood changes (dopamine, serotonin), loss of balance, slowness to heal, staying sick longer, sugar cravings, bigger appetite etc
What it does for us:
- It's essential for growth, repair and maintenance. Body replaces every cell in your body every 7 years.
- Causes biochemical reactions – digestion, energy production, blood clotting, muscle contraction
- Acts as messenger – hormones. Signals uptake of glucose into cell (energy)
- Signals breakdown of fat stored in liver, signals kidneys to reabsorb water, stimulates release of cortisol, stimulates growth of tissue and one
- Provides structure - keratin (structural protein - skin hair nails), collagen (structural protein of bones, tendons, ligaments and skin), Elastin - allows tissues to be flexible - lungs, arteries, uterus...
- Maintains proper ph - essential for correct hemoglobin balance that makes up red blood cells
- Balances fluids - albumen and globulin help maintain fluids by attracting and retaining water. Lack of can lead to edema and swelling
- Bolsters Immune Health - proteins help provide immunoglobulins or antibodies to fight infection
- Transports and stores nutrients - proteins carry substances throughout your bloodstream - into cells and out. Things like vitamins, minerals, blood sugar, oxygen...
- Provides Energy- It can provide the same energy as carbs but you don't want it to as it's essential for other roles. In a state of fasting (or insufficient protein) your body will break down skeletal muscle to provide energy - leads to weakness and fatigue.
Protein will:
boost metabolism and aid fat burning.
reduce appetite, hunger and food cravings
lower blood pressure
help maintain weight loss
help repair after injury
help you stay fit as you age
be good for your bones
Runners/athletes need 1.2g per kg of body weight
per day.
For me that’s about 90g. I need to eat 30g per meal. Not all of it in one meal
as it’s not stored by the body (unlike carbs).
A typical cereal breakfast with milk gives you 10-15g of protein. Not enough.
Eggs give about 8g. Bacon slice about 5g. Wholemeal bread slice 4g. Or if you
can’t eat that much go for a protein shake?
Then another 2 meals in the day each with 30g of protein.
There is no point fasting for the day and then eating a huge meal with 90g of protein in the evening. Your body needs it in small equal doses throughout the day.
As was said above, if you don’t eat enough protein then recovery will be less assured and so will
be the benefit of your training. Why train hard and then reduce it's benefit by eating poorly?
Some examples of good protein providers:
Fish, cheese and all kinds of meat are over 20% protein. Eat 100g of chicken say, and you'll get 20g of protein.
Eggs are roughly 15% protein. Oats 17%. Bread (wholewheat) 11%.
Nuts and beans have roughly 15-20% - peanuts, almonds are high in protein as are sunflower seeds, chickpeas, and kidney beans.
Fresh vegetables and fruit are low in proteins generally but provide other important nutrients.
Have a good look at the nutritional value on food packets to get more ideas. Some are well set out to tell you what a portion is giving you:

Running faster
Running 2021
On Wed 2nd June this year I ran the Hereford 5k in a time of 18:10. Although this is 40 secs slower than my PB at age 46 (I was late to competitive running) the time gave me 90.45% on the WMA age graded calculator. This is the highest I've ever achieved and was the first time over 90%.
Many have asked. How? What am I doing now to achieve this?
Like all answers to 'what is the meaning of life and everything', it's not as simple as just responding with a single reason, like '42' (you have be a certain age to understand the reference).
So here are some reasons why I'm in a bit of a purple patch at the moment:
1/ Distractions. During lockdown with travel restrictions in place many of my usual activities took a back seat so running became a bit of a focus. There wasn't much else to do.
2/ Buddy. Cherry and I live within walking distance and did a fair amount of training together. Being similar speed really helped too - in speed training we are evenly matched. Like running with club mates generally, running with a buddy helps keep you motivated/interested.
So, rather than running just being one of many things to do, it became a focus, and having someone close at hand who is the same speed gives you added motivation and makes your training more specific to your needs.
3/ Other stuff:
- Complementary activities in the week - mtb biking x3, hill walking, climbing, gym sessions x2, yoga ... all help with recovery, muscle recruitment, balance, core strength, mental health etc. I have had osteoarthritis in both hips since early 30's so have to keep weekly running mileage down (so no road maras for me). I have an arthritic big toe that limits off-road running distance and calf muscles that ping when running fast. The complementary activities have helped keep these issues under wraps for a while.
- I plan my running week and know my limits - for me one long run, one speed session and one tempo run is the plan. I try to vary the surface - long runs in the hils are ace. I know I can't even do a recovery run the day after a race. I'll break.
- Diet is a big influence on performing well physically. I do think a lot about what goes in... since our bodies are constantly being re-made (old cells are excreted and new ones created) it makes sense to make the new you out of good stuff. Beer and peanuts are my downfall.
- Rest and relaxation - sometimes I just do nothing, read, write, create, socialise, do mental challenges/problem solving ... it all helps to keep me sane. I strongly believe we all need challenge in our lives to help put things into persepctive. Some anxiety and some stress is important. Not too much obviously.
- Do it the hard way - why park close to the supermarket entrance. Park at the far end of the car park. Don't walk the direct route. Go up and down hill to get there. Don't sit. Stand. Holidays are are not 'down time'. They are adventure opportunties.
- ebike. This is my secret weapon. I can bike everyday - even the same day as a hard race - I just turn up the power. It definitely aids recovery.
- Being retired - some have said when you retire you have more time to train. I actually run less than I did when I worked. But I do have more time to look after myself. I need to. I'm old!

Damp
Damp Prevention in your home
Damp patches 1 metre and above floor level
Damp patches on the 1st floor ceilings are likely to be associated with leaks in the roof or leaks from water tanks/plumbing in the roof void. Most roofs leak at joins - either from one section of the roof to the other (valleys) or around chimneys.
Damp occuring on walls in kitchens, bedrooms or bathrooms could be due to leaking guttering, leaking plumbing or damaged cavity trays on the top of windows... but are more likely going to be caused by poor ventilation in your home. Everyday living in homes produces huge amounts of water vapour. If it can't escape it will condense on cooler surfaces and eventually look like water running down the walls. This ultimately leads to mould growth.
If you currently dry your washing on radiators or an 'airer' then this will contributre to damp inside your home - the water that was once in your clothing becomes water vapour and unless it can escape outside will condense back into water on cool surfaces within your homes - walls/windows etc.
In years gone by adequate house ventilation was not properly understood. The developement of seals on windows and doors and draft excluders all remove accidental and passive ventilation. Modern building regulations ensure that houses built now will have ways to properly ventilate homes. Houses built before 2000 may have little or no provision for ventilation.
Bathrooms and kitchens should have a fan fitted to remove water vapour in the air. Cooking produces a lot of water vapour and a properly fitted cooker hood vented to outside will drastically reduce damp problems in your house. A fan in the bathroom (activated by the light switch) will remove steam/water vapour from bathing and showering and also help to reduce condensation.
If your home has both a cooker hood vented to outside, a bathroom fan, you do not dry clothing inside... and you still get damp/condensation problems, then it's going to be a good idea to fit futher ventilation systems. Opening windows isn't always going to solve the problem and in the winter will lead to much higher energy bills. A whole house MHRV (mechancial heat recovery ventilation) system will solve all condensation and upper wall/ceiling damp issues (not relatd to leaking roofs/plumbing). See previous blog post for more information on this.
Damp near the floor - risng Damp
If you own a fairly modern house it is unlikely rising damp will be an issue. For quite some time, houses have been built with a DPC - damp proof course. Ths is a non-permeable barrier built into your walls roughly 150mm from the ground. Damp (water) will naturally permeate through stone/bricks from the ground up through walls to height of about one metre above the ground by capillary attraction. The DPC stops this flow and keeps your walls dry - inside and out.
If you have an older property then rising damp can be a problem as the stones for the walls were often just laid directly on the ground, often with little or no foundations. Also, ground levels may have changed over the years and can end up be above the ground level inside your home.
If your walls are damp near the gound, you get mould growth or the surface gets pitted and flakes off then you will probably have rising damp problems. This will contribute to the water vapour in your house and this can lead to condenasation issues elsewhere and health problems for dwellers.
Remedies
There are many ways to rectify rising damp.
Some advocate injecting a damp proof barrier in the wall with silcone. Ths can work in some cases but it all depends on the construction of the wall. It may not work well for a traditional rubble filled stone wall as the injection process may not proof all areas of the wall, leaving a gap or bridge where the damp can travel past.
Many try to cover up damp walls using a waterproof plaster or cement based covering. In my experience this is rarely a permanent cure as the damp will just permeate to other places or eventually find a way through.
In my opinion, the best way to deal with rising damp in older properties is to fit a barrier preventing the damp from coming inside. The moisture is alloweed to travel into the wall naturally, but you just stop it from spoiling the inside. Basically, you 'tank' out your floors and walls with a plastic membrane to a height of 2m above ground level. It is though, a lengthy process and if you can't do it yourself will
incur high labour costs. However, it is the belt and braces 'proper
job'.
The black plastic on the walls here is Oldroyd and has the benefit of being very strong, easily folded and having a ribbed surface to aid water transporation downwards. |
This membrane can fit over existing plaster (or you can remove it if it is particularly damaged). Fitting the adjoining membrane on the floor will mostly entail breaking up and removing the floor - but this depends on both the headroom of the rooms in the house and the floor construction.
Since there may be condensation behind the membrane on the wals you need to provide a way for water to escape - this can be done in two ways: provide a way for water to pass directly into the ground via a layer of gravel; or create a drain system that collects any condensate and diverts it to outside. This drainage is of course all below the floor membrane so no moisture can make it's way into the room.
There are various options to cover the wall membrane to produce the standard smooth plaster finish. Some membrane sytems allow you to plaster directly on them. Or you can add wood battens to the wall using the existing plugs used to hold the membrane to the wall (they are specially designed to allow screws to be fixed into them).

MHRV
MHRV
Mechancial Heat Recovery Ventilation
I've installed a system in each of the last 4 houses I've owned.
The need for good ventilation provision in houses is one of those things that in the last 20 years is becoming better understood.
We've all seen pictures of mouldy walls and windows in bathrooms and probabl;y experienced condensation on windows and mouldt grouting in bathrooms and showers. Having too much water vapour in your home can damage furnishings, decoration and even the structure of the house.
With MHRV you'll never get mould issues, condensation on windows, lingering smells from cooking and in toilets. After a shower the cubicle will be dry within an hour and it'll be fine to dry your clothes on radiators within the house. Fresher air with normal levels of moisture in your home will bring noticeable health benefits.
An open window or trickle vents integrated into new windows do give some passive ventilation but in the winter heat will escape and you'll get cold drafts and good air circulation/replacement is not guaranteed.
Why ventilate?
Apart from having fresh healthy air in your house to breath, a noticeable lck of smells from cooking (and from the loo) the main benefit is the removal of water vapour.
During the day the average person produces 3 litres of fluid in the form of water vapour from breathing and sweating. Add to this all the water that escapes into the air during cooking, washing up, showering (and the drying of the cubicle after) and drying clothes and you have a huge amout of water in the air in your house. If this water doesn't get out of your home it will be find it's way into your furnishings, wallls, roof space etc. and will condense on cooler surfaces. This can lead to mould growth and very unhealty living conditions.
MHRV basically constantly replaces the air in your house with fresh air from outside. The air is replaced roughly once per hour.
Each room has a vent in the ceiling/wall. In the rooms with the greatest amount of water vapour - bathroom, kitchen - the air is sucked out. Then normally drier rooms like bedrooms, living room have air pumped in. Therefore there is a flow of air from those drier rooms into the wetter rooms. The flow of air is very gradual and you are never aware of drafts. Clearly if a room door is very tight and there is no gap underneath, this will inhibit the circulation of air within your house. Sometimes installers will put vents at the bottom of some doors if they are going to stay shut for a long time.
You may be thinking that surely if you suck out the warm moist air out of the wetter rooms and send it outside then surely the heat is lost and you're going to get cold air coming in to replace it.
No. The air that is sucked out of wetter rooms travels in ducting that all eventually join up and lead to the MHRV unit. Inside here, the warm wet air passes into a heat exchanger where at least 85% of the heat is passed onto the cold air coming in from outside. The two air steams do not mix as they are kept apart by the thin walls of the exchanger - only the heat passes from one to the other.
Yes some heat is lost, but this is far less than having windows partially open or other forms of passive ventilation like trickle vents.
One of the myths about with ducted heating and ventilation is that it can lead to mould growth inside the ducting which could harbour germs and heath risks like legionella. The ducting never gets damp as it's insulated and the flow of air within ensures no condensation occurs.
Fitting and costs.
The cost of fitting a system will be easily recovered in the coming years by reducing your heating costs, redecoration bills and avoiding potentially costly structural repairs to your property. Plus, it is likely your health will improve.
If you have a standard house with a ground floor and a 1st floor then the MHRV unit may be best positioned in the loft (roof space). Getting the ducting to 1st floor rooms is easy at it will simply snake it's way within the roof void to each room. Routing the ducting to ground floor rooms will be more tricky and may require some light building work - boxing in the ducting as it travels through 1st floor rooms on it's way to the ceilings in the ground floor. One way of disguising the 'boxing in' is to simply extend a chimney breast by 250mm with some battening and plasterboaad - this way no one will be aware of any change. Other than that it might be possible to run the ducting down the corner of a room next to the doorway or wthin a built in wardrobe.
If your system is properly fitted few people will even know it's there. The small circular vents in the ceilings in each room are the only visible signs.
The MHRV unit will produce water as the warm air removed from rooms can be saurated in water vapour. This may condense within the hear exhanger. It's all perfectly normal and every system has a way of collecting this and draining it out. Therefore you need to ensure your MHRV unit is placed in a convenient location for these condesates to be drained to the house drainage system - the bath/basin/shower waste for example in the bathroom.
Cooker hood: some advocate integrating the extractor from your cooker hood into the MHRV system. This can indeed be done as the heat from cooking can be utilised to heat up the incoming air. However, it is very important to have very good filters in the cooking hood (which are regularly cleaned or replaced) as you do not want vaporised oils and fat entering the ventialtion system as it will deposit on the ducting walls and the heat exchanger unit resulting in poor performance and eventually failure of the unit.

Kitchen
Why get new kitchen cupboards when you can just paint your old ones. The paint is very robust and is similar to 'hammerite' in application. No brush strokes can be seen.

Solar PV
PV solar panels produce electricity which you can either use yourself or export to the national grid.
In 2011 you could get 40p for every Kwh you produced from solar panels fitted to your home.
In 2018 it's 4p for every Kwh you produce and a further 5p for every Kwh you export to the grid.
These payments are referred to as FIT (Feed In Tariffs).
At first glance you'd think it's hardly worth getting them fitted nowadays.
However:
- PV solar panels have come down in price hugely
- If you can use a lot of the electricity you generate then your bills will be reduced significantly
- If you have a small pot of money languishing in a building society somewhere that you are using to generate a small income from (interest) then the investment is better off on your roof
- PV solar panels (that you own) can increase the value of your property
We had 10 x 0.295 kwh panels fitted. So, on a sunny day they can produce 2.95 kwh.
It's estimated that in a year we would produce 2579 kwh.
2579 X 4p = £103
It is deemed that we would export 50% of this to the grid and use 50% ourselves.
The equipment installed can't actually measure what is being used or exported, the FIT is based on the the assumption that we would export 50%, and the FIT payment to us is based on this.
So 1/2 of 2579 X 5p = £65.
A total income through FIT of £168 per year. Not a huge amount - but the key point is:
Any of the electricity we use, of that we are producing during the day, is free to us. So the electricity used to do the washing, or heating water etc etc during the day when we are producing electricity from our panels costs us nothing.
It is assumed we would make a saving of £144 in the year.
I personally think it will be much higher, as we are totally electric - water heating, space heating etc is all using electricity. I think the figure will turn out to be nearer £160+
The system cost £6050 to fit.
In a year the panels create £144 + £168 = £312.
If I keep the £6050 in the building society I'm lucky if I can get 2% on the investment.
By investing the money in solar PV I'm effectively getting a minimum of 5.1% .
It is as they say a 'no brainer'.
Additionally, the panels will increase the value of the house.
It also feels quite nice to be producing and using electricity that is less polluting in the long run.
Further details:
- Our system was fitted by EON. The cost stated above includes everything - fitting of panels, erecting scaffolding, providing all monitoring equipment etc
- We chose an expensive system with higher output panels and a long life inverter. You can get a similar but cheaper system for around £4300.
- The system we bought is particularly good if a shadow falls on any of the panels - in simple systems if you get a shadow on one panel the whole array will not produce any electricity. We have a cheeky telegraph pole that casts a shadow on the roof for part of the day.
- Our inverter is said to have a life of 20 years - cheaper ones only 5 years
- Using the electricity you produce is the key to getting maximum value from the panels - could you heat a hot tub, charge your electric car?
- The system we have - Solar Edge - comes with a smart phone 'app' that tells you how much electricity you are producing, how much of it you are using and also shows your total electricity consumption - all in a nice little graph. It shows all this for each day, or week, or month or the year. Great for 'technogeeks' like me. In the screen shot below you can see that as it was a cloudy day we were only producing 300w and using 3.14 kw from the grid.
- Very soon it will be worthwhile getting batteries to go with a PV array. This will mean being able to store electricity produced during the day and then using it to run appliances at night time or when there is no light. Lithium Titanite is on the way. These are very safe (unlike lithium ion), can charge very quickly and have a cycle life of 3000-5000 times. When the prices come down, battery storage for PV will be viable.

The next renovation project is underway
3 bedroom property in Lydney. Two minute level walk to Tesco and the sports centre. Next to the park. Walking distance to train station.
Needs complete modernization.
Currently has very small downstairs bathroom - will become cloakroom
Needs rewiring. New Kitchen and convert upstairs bedroom to bathroom. Extension. New ceilings. Completely re-plastered. All new doors, skirting etc. Roof not bad, floors OK. Windows fine. New front and rear doors. New combi-boiler and pipework to radiators. New water connection (as old is lead into property).
3 years we reckon.
We took two weeks removing many layers of wall paper, removing mouldy carpets and rotten skirting/architrave.
Stripping out old water tank (gravity fed from header tank in small bedroom).
Joc removing wooden coving and strange wooden strips that criss-cross ceilings.
It took 3 years in the end. It provided hours of entertainment (ha), took a huge bite out of savings... but ended up pretty tidy:
All new kitchen |
Dining area other side of kitchen |
Lounge |
Hallway with new doorway to downstairs cloakroom |
Cloakroom |
Master bedroom |
2nd bedroom |
Upstairs bathroom |
New van conversion complete
The van was finished early in 2016.
We spent heaps on it... but if you're going to use it it's worth it!
It's been to the Lakes, Dartmoor, Exmoor, Beacons, Alps etc etc.
It certainly is a more economical version than the old T5. One trip up the Lakes at 70mph on the motorway saw it average 43 mpg. But it's not as 'pokey' as the 5 cylinder engine in the old one. The 'bluemotion' mapping means it's harder to accelerate from a stop, but the 140bhp gets it up the hills well. Being newer, its much smoother and quieter generally.
Cruise control and air con is essential on those long journeys.
In this version we have a back cooker and sink accessible from under the rear tailgate.
We have the same 2x single bed configuration with front seats on a turntable.
Table goes up on drivers side
SCA pop-top gives good headroom when parked up...
And a double bed upstairs
And we decided on a compressor fridge that runs off the leisure battery.
Love it. Why doesn't everyone have one?
