Why ride 2 × 15 Threshold?
Hard intervals near your functional threshold power. They train you to hold high power for longer, and they demand real recovery.
When to use it
On a dedicated hard day, usually no more than once or twice a week.
Recovery
Plan at least one easy day afterwards, two or more if your legs feel heavy.
Riding tips
- Ride it in ERG mode: YourIntervals sets the resistance for every interval, so focus on a smooth, steady cadence around 85–95 rpm.
- Targets feel off today? Use the intensity control to scale the whole workout up or down in 1 % steps.
