Solo group ride

It's sound like an oxymoron, but it describes what I did this morning. I'm still tied to the trainer in the basement, and need to find ways to keep myself entertained. One of the best ways is the Tacx RLVs. So today I was invited to join the Tacx Triathlon team for a group ride around the bike course of Roth Ironman course. I did the whole loop straight through (previously I had only done portions), for a 2:34 ride. I turned the effort down by -20%, and it was still plenty of work, and it still taught me a couple of important lessons.

Because I can't coast with pausing the ride, while the computer riders were cruising downhill, I was pedalling along at 170w behind them. It may have been easier than the rest of the ride (average 198w), but I sure was jealous. No wonder I'm tired. It's like doing the whole ride on a fixie.

The other thing was how much the few accelerations kill any running legs. I didn't bother testing things on the treadmill, but I could feel as I was riding, that each time we went 260-320w up the climbs, or during hard TT efforts, I was using up a lot of running juice. Sticking around 200-210w could be done all day, but it really was those FTP+ efforts that deaden everything. That will be big for me to remember for my longer course races this summer, especially over the rolling terrain of Muskoka.
