Sounds like a fun weekend Hermes. Three hour rides provides a lot of time for other fun activities. Our leader at the trainer class is having the A group attempt to do the OTS intervals at 80 to 85 to 90 rpm in progressively longer intervals starting at 1:30 for each cadence working up to 3 minutes or 9 minutes for the set. In the past I was very happy to plod along on the OTS work at 65-70, but that is no longer good enough.

I'm having trouble with anything over 80 rpms when OTS. I know it is a lot easier on the road when you can swing the bike to allow the hips to push over the top.
I'm still over a month away from the first race of the season in mid-March. It is one of the two races held on the Mid-Ohio Sports Car Course. There is the usual 50% chance of it being postponed due to snow.
