Over the summer months I've got into the habit of going for a run on a Sunday evening pushing my 2 year old son around a flat 6 mile circuit in his buggie. My hear rate stays low (65/70%).
I do this run after a hard morning session of either a long run or a race. I feel very relaxed during & afterwards but was just wondering if it was doing me any good. I'll keep doing the run for the rest of the summer because we both enjoy it, but is it helping to build aerobic endurance or just tireing out already tired muscles?
