10 x 1 minute efforts, 1 between

In the 60's and not raining so I hit the crit course to do these. Felt pretty strong: 511-530-525-524-509-519-530-507-509-513, or 518 average. Looked back and found the same efforts from last April 29 averaged 505. I have a few more sets of these over the next two weeks so will attempt to build on them.
