15x1 Power Intervals

Hadn't done this in a long time. Also rode inside for two hours first, one at 170 and one at 140 or so. I did these outside at Ault Park going clockwise starting each at the bottom of the loop, finishing behind he pavilion and coasting back to the star.Temperature was about 35 degrees. Avg watts on each: 510, 482, 489, 528, 526, 511, 516, 536, 514, 526, 528, 526, 536, 541, 530; NP of 421 for 44 min, 421; 520 avg on the intervals. Avg cadence around 95-100.
