Question: How do you feel about bicycle training to improve running?

Sri Chinmoy: I did a great deal of bicycling when I lived in India in my youth. For at least two and a half hours every day I used to cycle as I did errands around the ashram. It does not increase running speed at all, but something is better than nothing. Sometimes cycling can actually be a hindrance to running speed, because it develops special kinds of muscles which do not complement the speed muscles. Bicycling does help for endurance, but if you want to increase your running speed, then I don't advise it. You can cycle for endurance, or if you are injured and cannot run. For a little bit of stamina you can do it. But again, cycling stamina is totally different from running stamina. If one wants to become a good runner and maintain a five-minute pace, then cycling is not the answer. Quality road work is the answer.
