I’m liking this stuff. Today, I decided to try to use the treadmill.
So, I set it up for a 15% grade and started walking at a nice gentle 2.5mph pace. After 4:20, I turned up the speed. The first interval I got up to 6.2mph, and sprinted until the next minute turned over. I got just over 30 seconds of sprinting at speed, and then I hopped off the belt to the sides and turned the speed back down. Then I’d walk it off for the next 4 minutes. I boosted up the speed a bit on each of the sprints. The surprising thing was that my sprinting economy improved through the session, so I found it easier later on even though I was up to 7.4mph by the last interval.
Overall it was a bit easier from an aerobic perspective than yesterday, but a hell of a lot more fun.
Tomorrow: I have a 7:50AM flight from LAX to Boston, so I need to leave the hotel before 6am. I get home around 6pm, so probably no training.
