Speaking of winter, today we got another taste. It didn’t snow, but we did get a blast of arctic air. The temperature this morning was 16°F and it only reached a high of 29°F. So it was another indoor workout for me. I just did a set of 2x20s. Since I was indoors, their wattages weren’t anything to write home about. My LTs on the road are almost always better. I warmed up and did the first one on our Cycle-Ops Fluid trainer and then switched over to my Kreitler Rollers for the second one. I just wanted to see if one felt easier than the other. Well, I don’t think it made a bit of difference—they both were hard. The first interval felt slightly easier, but that was probably due to being fresh. I will have to say that the Kreitler rollers feel much more realistic. Not just because the bike isn’t locked in and you have to balance, but the resistance itself feels more like riding outside. Those 4.5″ aluminum rollers plus the Killer Headwind fan seem to provide just the right combination of rotational inertia and resistance. I switched back to the trainer after my intervals for some added saddle time for a total of 1hr 40mins and 111 TSS.
