Uh no. Smaller environmental effect = smaller variance in times = less need for some alternative form of measurement. I don't know how this can be said any simpler: for running, a stopwatch is generally precise enough. For cycling, it isn't. Why? Because an individual's cycling speed will vary far more do to outside influences which, in turn, makes speed an unreliable way to measure progress.
