Here's my question - to what extent does training on a bike prepare you for running and vice versa?
I'm a runner, not a cyclist. I've been running for many years but recently I've gotten lazy with it and have been spending a lot of time biking. II have some races (running) coming up this month and I'm worried that I might not be up for them because I keep stubbornly biking instead of running. From a cardio standpoint, I'm guessing the two things are quite similar and one of them can prepare you for the other. Am I wrong in thinking that? But then there's the muscles that are used in each. Is cycling helping me to run?
