I managed to get back on the rollers for a second session for a total of 2:55 for the day
Still a little bummed I failed on the 20s, but I guess stuff just happens. My norma hr for those is around 165 and today it was up to 172 after only 10 minutes. My heart actually hurt (rather than my lungs or legs), it was weird.
Tomorrow I'm going to brave the crappy roads to get in my last force hill repeats. Then next week I'll start doing 2 threshold sets a week (2*20 and zci) and one vo2 session. 1 month until racing, can't wait.
