4x 5min Threshold Intervals

Spending time riding at your Threshold will enhance your ability to ride at Threshold. It will allow you to tolerate lactic acid, clearing it more effectively, lifting your Functional Threshold Power (FTP) and also moving your Anaerobic Threshold deflection point to the right. Both these things mean you will be a fitter more effective cyclist. This workout will benefit all cyclists - road, mountain bikers and triathletes.

The Warm Up (WU) should be done at an intensity that is steady but not over consuming at Level II, riding for twelve minutes.

Prior to the main set we will go through a little ramp where we ride at Level III- for one and a half minutes before riding at Level III+ for a further one and a half minutes. We continue to lift our intensity with a minute at Level IV- and then another minute at Level IV+.

Take a five minute Rest Interval (RI) riding at Level II before commencing the main set.

The main set is made up of four reps, riding at Level IV for five minutes with a two minute Rest Interval (RI) at Level II after each rep.

Conclude the ride with a cool down (CD) of ten minutes riding at Level II.

Finish with ten minutes of stretching to assist with the recovery.
