Very very interesting edition of the Food Programme on BBC Radio4 just now about food, sports nutrition and how it effects running. It'll be on iPlayer a radio in a while and its well worth a listen. Discussion about the merits and otherwise of high carb vs high fat vs vegan and vegetarian diets and their effects on pace and endurance. There'll be a follow up programme next month after some of the diets have been put to the test. Interesting stuff!
