Three sets of thirteen 30/15s at 122% FTP — the interval protocol from Rønnestad’s research showing superior VO2 max and performance gains versus traditional 4×5s.
Repeat 3 times
Repeat 13 times
VO2-focused intervals raise aerobic ceiling and repeatability for attacks, climbs, and hard surges.
Useful when you want sessions that match tags such as 30/15, VO2 Max, Rønnestad, HIIT.
