Wednesday Windtrainer Workout: Zwift Academy 2021 Threshold Under/Overs

Riding at your threshold is important to develop your ability to maintain your maximum steady state. During these Under/Over intervals your body will adapt to the level of lactic acid in your blood system, developing great tolerance. This session is great for triathletes, road cyclists and mountain bikers.

Each Wednesday I’ll post a Wind Trainer session that you can do in about 60 minutes to enhance your cycling. See a previous post about training intensity (Levels) to know how hard to work. If you are working directly with Coach Ray he will in most cases prescribe either a Power Zone or Heart Rate Zone to work within if you are training with these tools.

The inspiration for this session comes from Watts On Zwift. I’ve modified it a little bit. You can read the full article here. The session itself was designed by Stephen Gallagher and Dan Fleeman from Dig Deep Coaching.

Check out last weeks workout here:

  • 3min Level I;
  • 6x 1min Level IV-, 1min Level IV+;

Start the workout with a ten minute Warm Up (WU) riding at Level II. Keep your cadence above 90Rpm for the warm up.

Next ramp things up to Level III for one minute.

Next up is a Rest Interval (RI) at Level II for three minutes, keep your cadence up above 90 to keep the legs fresh, because the hurt is going to come.

The main set is made up of two sets of six reps. Each rep is made up of one minute at the bottom end of Level IV, followed by a minute at the higher end of Level IV.

Ride for six minutes between sets at Level I for your Rest Interval (RI).

Conclude the intervals with ten minutes riding at Level II for your Cool Down (CD).

Finish with ten minutes stretching to assist with your recovery.
