Felt pretty tired today (maybe donating blood contributed). I've also been feeling weakness in my right inner hip flexor and lower back. Due to steady rain, I ran on the treadmill. Started slow and didn't pick it up much, but I did extend past the planned 5 miles. Stopped at 8 miles, 8:40-8:25 pace.
I had my body fat measured today. Back when I was training a lot and running ultras, I was generally 6-8%, which is very thin. As I ended my career in 2014/15, I had inched up to 10-11%. I'm now 20 pounds heaver and measured 17%. I guess that's still less than 82% of population, but higher than I'd prefer. Donuts just taste too good, and frisbee doesn't burn as many calories as straight running.
