Yesterday, Fiesta road bike. I was not sure what I was going to do until I got there and checked out the wind. I decided on big gear work and then wished I had brought the TT bike with the 54 chainring versus the 50t on the road bike. I did a warmup and a couple of jumps and then 4x4' tempo power @ 55 to 60 rpm with a 10" sprint (max effort) at the end of each interval in the big gear with 3' RBI. And of course, I rode the efforts and sprint at the end in the drops. It does not seem like a lot at the time but quite fatiguing.
