Hi Im pretty new to cycling and I'm really wanting to try and get my fitness levels up. I have recently completed a 28 mile run and crikey I could of one passed out and come the end, my legs were trembling. Tonight I done 10 miles and I was fine. I am ideally looking to get my fitness levels up enough to manage a 38 mile round commute to work a couple of times a week, does anybody have any tips? I.e. Training and what foods are best?
