12x30 seconds, 2 sets

I did these inside as it was too cold early in the morning (30's). Pushed cadence above 125 on most, averaged from 26mph to 29 mph (second set mainly above 28) and power in the low 400's. In a typical 30 second all out I'd be 600+ but looking more for that high blend of cad/speed/wts in rapid fire sequence over two 12 minuet sets.
