So I managed the 5.5K and the 2.5k, but I went out to do the 5k today and only ran 4k. It was SO hot. 25 degrees here today. I usually run in the afternoon but maybe on hot days I need to reschedule to the evening. I picked a shadier trail but it was very uncomfortable. I did walk 1.5k at the end but I'm wondering if I should repeat week 1 of the 10k plan or just move on to week 2? What would you do?
