Ran on the treadmill in the hotel. I substituted hill repeats for hill repeats on the treadmill. I did 10 x (1' hard @ 5% and 8 mph + 1' easy @ 1% and 6 mph). All the pace and incline changes kept me from getting bored as I had to watch the time closely, and account for acceleration/decceleration of the treadmill. It was a hard workout. The room was air conditioned, but I was soaked regardless. According to Jack Daniels, 5% and 8 mph are equivalent to 6:11 pace, but I don't know, it seems too fast. |
