Short 5 - 20 second sprints tonight, perfect for filling in my power curve's short end. The shortest sprints were mislabeled, though. They said 10 s but were really 5 s. It took a bit of getting used to to get them in smoothly. I got all the stars save one (and a half) because of a couple of very short segments at very low power whose presence I don't understand. They were just too short to adapt to. I chose the Innsbruck Lutscher route. By Zwift reckoning I only went 9 km and only just arrived at the start of the official route at the top of the mountain. Garmin puts me at 21 km for the same (presumed flat) effort. Made a bit of a ride/walk brick of the workout, as I needed 2 km of steps to get that goal in, too.
