Week 9 runs 1 and 2 completed.Both around a local playing field perimeter path. I was thinking of two options for my final( graduation) run, the local parkrun or at the gym on the treadmill which has a 5k run program on it. Unfortunately couldn't make the 9am parkrun start this morning due to family reasons. As all my other runs have been outdoors is it OK to do my final run at the gym? what do others think?
