Why ride 3 × 15 Sweet Spot?

Challenging but controlled intervals just below threshold. Sweet spot builds sustained power and muscular endurance, usually with less recovery cost than threshold or VO2max work.

When to use it

Once or twice a week when improving sustained power is your priority.

Recovery

Most riders are ready for another quality session after one or two easy days.

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.
