I’m using the very simple smartcoach program at rw.com for my marathon training. You enter a recent race time, desired training intensity and long run day. It then gives you a schedule that brings you up to race day, together with predicted time.
According to the plan I should have started last week, and had a 13km run on Saturday. Yeah right. All I did was the 8k on saturday and the 5k race on sunday. Missed today’s 5k easy run too. Sigh. Not good.
