Did 5 mph/8 mph intervals again today. Pushed the first 8 mph interval up to six minutes. Survived it and it was actually a little easier than last week.
Next week I'll try pushing the second interval up to 6 and see how it goes.
Just out of curiosity, how did you pick 5/8 for your intervals? Just what felt comfortable? Or did you read that somewhere?
