Rode a couple of hours inside early in the a.m. since it was too cold for me to head out (20's). Once it warmed up I went to Ault Park to do some 12x1 power intervals. Started at the bottom of the loop going clockwise and took each to the back of the pavilion, coasted to the bottom and then did the next. Power averages were 489, 525, 509, 504, 491, 495, 495, 479, 475, 475, 492, 488 and 464. Much better than inside and pretty comparable to efforts done in years past.
