Working through myasics plan for the London winter run I came across an article on overcompensation and the importance of rest days. Basically it says training damages your body and the rest day lets it recover but also your body then overcompensates and makes it stronger so that it won't get damaged as much next time. So the rest day lets you repair the damage a run does but also makes you physically stronger for the next run. Makes sense really and shows you how you improve your fitness over time as long as you take the rest days. Full article is here asics.co.uk/sports/running/...
Happy running and resting all
