What is it with me and cycling? I can't bloody do it. I'm fine on the flat and over little undulations, but the first tiny little excuse for a hill and my legs give up. It takes a few strokes for them to start burning and stiffening and I just can't keep the tempo up. I'm an extremely stubborn person but they defeat me every time. Fitness-wise, I'm not a superfit ultra runner but I'm not Wayne Slob either; I'm a bit puny but I've obviously got some muscle on my legs for hopping up hills, so what the chuff is going on? Am I just feeble or am I doing something wrong? I know there are some two-wheeled warriors on here - any advice would be appreciated.
