Those type of runs are hard. When my legs are heavy like that, if I make it 5 min I'm lucky.

I meant to just walk today, but I started the 10K runner program on autopilot, and I decided to see if I could do the running. It was pretty much a duplicate of yesterday with a 3 min walk between the 2 running intervals instead of a 5 min walk. So it was a 40 min total run today broken up into a 25 min run interval and then a 15 min run interval. I did it, and it was another one of those really good runs where I felt strong and did not struggle near the end of the run. The program gave me a 53 min workout total, which is awesome, and by the time I'd walked home, it was an hour long workout.
