Cycled into work yesterday and did a couple of Centennial Park laps on the way home as well. Once home it was a quick change then out the door for a run. I upped my run/walk intervals to 7min running, 1min walking and it felt fine. Four of those totalled 5km and my legs are in good shape today, so things are looking up.
