Three weeks down and counting to the big trip and I'm vaguely nervous. I did 21 miles yesterday - pain free, effortless (ish) and came home with a massive grin on my face, fully confident that me and the gammy leg will soar up the steepest hill between Toulouse and Salzburg. Today though...knee aches. Feels a bit illio-tibial from what I remember from my running days. Also, the physio suggested I look into what foods and supplements I should devour whilst exercising and also to help the body recover. Any bright ideas? I was thinking carbs whilst exercising and milk afterwards but are there any supplements or things I should be taking?
