That's great news and thanks for sharing your experience. I must admit I've wimped out in the past and carb-loaded for running however am going to make a real effort to "train low, race high" next year (Mark Sisson's blog). My own experience is the same, I put on a stone (14lb) whilst training for my first marathon and only maintained during the second by very careful calorie counting on moderate carb - and again like you, find it easier to lose weight when not running. Completely counter-intuitive but true! All the best with your recovery.
