10 x 10 seconds

I rode an easy 30 minutes when I got up and then did these at lunch between meetings. I ramped up the rpm's and shifted up through the power range until I was above 600 and then hit the INT. Power was 664, 656, 613, 675, 648, 632, 640, 651, 624, 621. I took about 2:30 between each.
