About this workout

Many sprints are lost in the last few seconds, when the legs cannot turn fast enough to hold the speed. Spin-out sprints train that part. Choose a light gear, start at about 90 rpm and accelerate seated, pushing the cadence toward 130 rpm or more within 15 seconds. Four minutes of easy riding follow each effort.

The light gear limits the force and puts the stress on coordination and leg speed. You will feel the hips bounce when you reach your limit. Stay just below that point, and over the weeks the point at which the bouncing starts will move up.

The session suits intermediate riders in the build and peak phases, including track riders and criterium racers. It also works as a lighter sprint session in race weeks. Power targets of 150 to 200% of FTP are a guide, as leg speed matters more than watts here.

Tips

  • Relax the upper body and keep a light grip on the bars.
  • Stay seated for the whole effort.
  • Use resistance mode with a light gear on the trainer.
