This is my first post and I started the program in August. We I've been running 5k, 3 times a week for the last month. But I just can't beat 38 minutes. Whether i think I'm having a good or bad day - the result is always the same. I had an injury to my left foot 20 years ago, which means that all the bones in it are fused and i have very little movement. There is no spring in it at all. Could this be stopping me running faster or am i just a one speed jane? How do you get faster?
