There are time when I like doing these and times when I don't Today was a don't. hadn't had these on the schedule since January. I used my usual course at Ault Park starting at the bottom of the hill on Observatory and going to almost the back of the pavilion. While not fun I did hold better power than in january when I was in the upper 390's and low 400's Todays power was 470, 446, 444, 419, 426, 413, 425 and 408. My worst was better than my January best. But, these really hurt. Have another round tomorrow.
