Threshold intensity is race pace for shorter events. This session is fantastic for building fast biking and running off the bike in preparation for a sprint or Olympic distance triathlon.
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 an article by Dr. Martin Yelling from Yelling Performance and Elizabeth Hufton from an article in the June 2011 edition of Triathlon Plus.

Dr Yelling’s Race Replication Brick B

- 2 miles Level IV;
- 8min Level I;
- Bike
- 10 miles Level IV;
- Run

- 10min CD Level II;
- 10min Stretching
Start this brick with a ten-minute Warm Up (WU) at Level II on the bike. Lift the intensity to Level IV for ten-miles, then transition to the run.
Start the run with two-miles at Level IV. After the two-miles, jog at Level I for eight-minutes and reset up your bike.
Ride at Level IV for ten-miles and then transition again to the run.
Start the run with two-miles at Level IV, before dropping the intensity down to Level II for a ten-minute Cool Down (CD).
Finish with 10 minutes of stretching to assist with the recovery.
