Backing up off the bike

Rolled in from work, put on some running shoes and shorts, and popped out for a recovery paced 6km this evening - want to do a bit more of this 'twice in a day' stuff. It was pretty slow, with quads hit with hill repeats and 20k of hilly cycling through the course of the day completely uninterested. It was very slow initially, but I picked up a bit through the 3k mark and cruised home reasonably comfortably. Slow, but worth it.
