Although you are unlikely to race an Ironman 70.3 or Ironman at Threshold intensity (by definition it is impossible). Training sessions can use Threshold intensity to build you fitness, and in the same method as a rising tide lifts all ships an increase in your threshold intensity will also lift your overall fitness allowing you to race at a faster pace or higher intensity; or at the same pace or power for less effort. This is a perfect session for triathletes competing in Ironman and Ironman 70.3 distance events.
Each week I will post Monday’s Brick session that you can do to enhance your triathlon performance. For a full understanding of my Level’s intensity system, please read my previous articles about intensity for cycling and running.
The inspiration for this workout comes from needing a series of workouts for athletes competing in Ironman 70.3 events. I sat down with a pen and paper and planned a series out. This is the first of the Tempo Brick sessions that came from that planning time.

Coach Ray’s Threshold Brick C
- Bike
- 40min WU Level II;
- 3x 15min Level IV, 10min Level II RI;
- Run
- 2x 15min Level IV, 5min Level II RI;
- 10min CD Level II;
- 10min Stretching
Start this brick with a ride. The first 40-minutes is your Warm Up (WU) at Level II. Then increase your effort to Level IV for three, fifteen-minute reps. Ride for ten-minutes at Level II between reps.
After the third rep transition into the run.
Start the run at Level IV for fifteen-minutes. Take a five minute Rest Interval (RI) jogging at Level II, before a second fifteen-minute rep at Level IV.
Then move into a Cool Down (CD) for ten minutes at Level II.
Finish with 10 minutes of stretching to assist with the recovery.

“I was recommended to Ray by a friend. He gave me a plan which was essential for me to complete my first 70.3 triathlon in Taupo. My cycling has improved significantly due to his Velocity training sessions! He shared so many handy tips and tricks, and I appreciated all his encouragement to help me believe I could do it! Thanks Ray!” 🙌
Jason Ford
“So far for me, I’ve completed a half Ironman event, which I never thought I’d be able to do. I’ve got to the point where I’m comfortable swimming longer distances, lost about 10 kilograms. It’s good to have a personalized program that isn’t a one-size-fits-all, like you find on the internet… You’ve got an approachable coach who will take on your feedback and work with you around life. Just having that adaptability and personalization has really been key for me.” 💪
