Just listening to Chrissie Wellington talk about mistakes in training at about five minutes into pt1 I thought her comment would provoke some responses from the cyclists here. Near the end of pt1 she says biking improves running and vise versa. Is that true can any one back that up with studies? About a minute into pt4 she says powermeters aren't very acurate to how you feel.
