Windtrainer Session

Wednesday Windtrainer Workout: Gale Bernhardt’s Half Ironman Bike Intervals #2

Spending time training at appropriate intensities is important for developing your ability to ride at different paces or intensities in an event. For a half-Ironman event, you will spend most of the event riding at Level III (about 77-90% Functional Threshold Power). Even though this workout is designed for a half-Ironman athlete road cyclists especially those doing a century and mountain bikers can also benefit from it.

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.

The inspiration for this week’s workout comes from an Article by Gale Bernhardt in the May 2001 issue of Triathlete Magazine. This is an extension of last week’s workout:

Gale Bernhardt’s Half Ironman Bike Intervals #2

  • 10min WU Level II;
  • 20min Level III;
  • 10min CD Level I-II;
  • 10min Stretching

The warm-up (WU) should be done at an intensity that is steady but not overconsuming at Level II. Ride for a minimum of 10 minutes.

The main set: ride hard for 20 minutes at Level III.

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

Finish with 10 minutes of stretching to assist with the recovery.
