Quick question about The Cyclist's Training Biblehayaku

What's a BT workout? I know it means Breakthrough but what does that entail? I've looked several times but I can't find any information.
Thanks in advance for your wisdom and read-recall skills.

Friel uses the term to refer to any workout that include intensity levels of Zone 3 or higher. These are workouts designed to improve muscular endurance, power, or speed.
Thanks, I couldn't find it in the book either (nm)Aztecs

a BT workout is when you achieve or al least expect to achieve a result that you hadn't before. Maybe sustaining 5 min at zone 5 or finishing with a higher than ever average speed for your usual training route. BT workouts tell you that you have made progress.

Hi Hayaku,

Here's the definition from a coach at, Joe Friel's site:

"BT" stands for "Breakthrough", these workouts challenge the athlete, these are done in zones 3 through 5a. After completing a "BT" workout the recovery period is from 36 to 48 hours before the next "BT" workout
