Dr Yelling's Race Replication Brick C

Brick Sessions, July 18, 2025

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.

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.

Start this brick with a ten-minute Warm Up (WU) at Level II on the bike.

This brick is made up of three reps.

Each rep involves a ten-mile bike ride followed by a two-mile run all at Level IV.

After the run, jog at Level I for eight-minutes, prior to the next rep. After the final rep, Cool Down (CD) at Level II for ten-minutes.

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