I've done the entire Tough Love a couple times (2-3). Always alone.

I did the first disk of the Hardcore 100 -- a simulated century that runs about 5 hours if you do all three disks. The first disk was about 1:40 minutes but the intensity wasn't too bad. It's supposed to get more difficult as the workout progresses. If we get the snow storm that's predicted for next Tuesday and they close down the gov't, I might try to do the entire thing.

Since riding outside has been unsafe due to lingering icy conditions and extreme cold, I've been back to my trainer. My new favorite thing is to do a strength video (one of the ultra conditioning Spinervals) after doing another Spinerval.

I can't wait until temperatures moderate and there's no more ice/snow. Doing Spinervals is much tougher, mentally & physically, than riding outside.
