The mathematics of hills, horses and food

This long, dragging week has been plagued with sore legs muscles and an overwhelming realisation that the sportive on Sunday, in preparation for the Big One, is actually going to be harder. It has a 17% hill and three White Horses…White Horses are generally found on hills… and those are just the ones I know about. London 100, as this great blog explains, is flat then ‘bumpy’ then flat; a course split into three and within the bumpy third there’s three hills, two of which I have done – one of which was simple.    Sunday is going to be hard!   Sammy sent me some supplement advice earlier in the week which got me thinking about what I eat and drink on the bike. I think I take the right drinks out with me; one electrolyte drink and one bottle of water, however in this hot weather I need to get much better at drinking them. I also do my best to hydrate the day before… so Saturday will be all about water drinking and bike fitting.

As for food; I tend to take a banana, fig rolls, digestives and jelly babies then I will buy a packet of crisps about half way round. I haven’t had a gel for months – they are, frankly, disgusting. So, this runner’s blog made me very happy. It’s worth a read and advocates the use of Jelly Babies as opposed to gels; I don’t really feel I need to research the opposing arguments – what he writes is clearly absolutely correct. Jelly babies are therefore, here to stay. Or at least in my jersey pocket to stay, which actually considering how sticky they get in there, I may not have any choice about!

The blog made me think more about what I should be eating and I came to the conclusion that I should have 58 grams of carbs per hour of exercising. According to Google, which is also always right, fig rolls contain 11.9 grams each, digestives 19 grams and a medium banana 30 grams. Baring in mind my 20 minute rule, I should be eating just under 20 grams of carbohydrate every 20 minutes. I love this kind of maths!!! In order to keep the maths simple, I will just eat three digestives an hour!!! 

Maybe not… they are pretty crumbly and overly sweet. Fig rolls however are great for iron, carbs and they are bite sized! Therefore, I think if I stick to my current regime, which hasn’t made me sick, but become a little more regimental with it and with water drinking then I should be okay. The twenty minute rule worked great on the track but it hasn’t been put into practice very much out on the road (too many distractions). Sammy, you and I are trying this on Sunday! A Fig Roll every 20 minutes and half a banana an hour…
