@Discombobulated Yes, you are definitely right to be cautious when running on tired legs. That's usually when I trip too, near the ends of runs or walks. But way to go getting a 6K in! Heat is not easy for me either even though I live in a hot, humid environment.

I took a long power walk this morning, nearly 8 mi.! I didn't think it would be that long but I was feeling pretty good and I won't be walking much next week due to having a slew of early appts. and having to take my daughter to a very early AP test at the local high school one of the days.
