Designed to hone your after a higher load of work leading up to the sprint. This is another great one that simulates sprints in racing. Warm-up 10 minutes, and then 3 x 1 minute fast pedaling drills >110rpm, then riding for 3 minutes at your sweetspot, then 2minutes at FTP, followed by a 15 second sprint and then recovery for 3 minutes and repeat. Cool-down!
