This session is based on the favorite workout of Amelie Kretz, who is an elite Canadian triathlete competing on the ITU circuit.
The session is a great way to develop your ability to develop your top-end intensity and your ability to sustain it. Perfect for draft-legal triathletes, road cyclists, and mountain bikers.
Each Wednesday I’ll post a Windtrainer Workout 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.
I forget where I originally obtained the original version of this workout from – potential the Canadian Triathlon Magazine or maybe from YouTube. The original version of this workout I published back in 2016:

Amelie’s Intervals Minus
- 10min Warm Up Level II;
- 2x
- 3min Level IV;
- 8x 10sec Level V, 20sec Level II;
- 1min Level V;
- 4min Level II RI;
- 10min Cool Down Level II;
- 10min Stretching
The first 10 minutes of the warm-up should be done at an intensity that is steady but not overconsuming at Level II.
The main set Is made up of two reps. At the start of each rep, commence by riding at Level IV for three minutes. After the three minutes, you move into a sprint for ten seconds as hard as you can. After the sprint rides easy for 20 seconds and then repeat the ten-second sprints until you have done eight sprints, then ride for 60 seconds as hard as you can. To finish the rep you have earned yourself a four-minute Rest Interval (RI).
Conclude the ride with a Cool Down of ten minutes riding at Level II.
Finish with 10 minutes of stretching to assist with your recovery.
