Working beyond your threshold point will result in the accumulation of lactate and you will fatigue very quickly.

For a MTB rider, raising the power you can produce at this threshold is of paramount importance.

This supra-threshold session of 4x 5 minutes will have you working at just above your anaerobic threshold power.
