Anyway I’ve been really focussing on my diet. Quite a few years ago I met a fly fishing dentist from Romania who was a pretty serious hill runner, having been considerably overweight at one point. He recommended that I try the 5/2 diet. This basically is where you eat five days a week anything you want but two days a week you fast. These days should be non-consecutive.
I’ve done this diet a few times now, in fact it’s now currently my regular eating habit (although I still drink beer on “fasting days”!). A couple of interesting things happen - on the days you do eat you don’t suddenly stuff yourself, if anything you are less hungry, eat less and feel full quicker. But the really fascinating thing for me, is that the day after not eating and before I’ve eaten again I have my best training days - harder/faster on the bike, quicker runs. This I don’t understand, but it’s very noticeable and I have measured it many times. It’s certainly very interesting - and a thoroughly effective and easy diet to maintain.
One race this year - probably a 70.3 - I’ll try fasting the day before to see how this works.
I don’t know if any of you have watched Game Changer on Netflix which is basically about vegetarian diets and sports - well worth watching if you haven’t. And I can certainly attest to their conclusions! I tried this as an experiment myself 19 years ago and noticed that my runs were quicker (I was running 100 miles/week then) and haven’t looked back since.
Right... I’m going to go and jump on the bike trainer for an hour
Cheers, Paul
Some day we’ll all be dieticians 
I do a lot of walking but that's about it, my job is very physical.
