AI FTP Detection has new capabilities to help keep your training on track.

We’ve just shipped another round of updates to AI FTP Detection that aim to give you better training when you find yourself outside of the “bell curve” of standard athletes, and make using AI FTP Detection more convenient.

AI FTP Detection default when using Plan Builder

AI FTP Detection is now the default option when you build a plan in Plan Builder. This means you don’t have to worry about upcoming tests on your calendar, allowing you to get in productive training instead.

Note: This isn’t mandatory. You still have the ability to select Ramp Tests and swap those for 2×8 or 1×20, or just manually enter your FTP as well, but making it the default option makes it easy for most athletes and less disruptive to your training plan.

You can replace Ramp Tests in pre-existing training plans by clicking your plan annotation on Calendar and selecting AI FTP Detection:

Edge case handling

If you are outside of the Specialty Phase and you complete a Level 9 Threshold, VO2max, or Anaerobic workout, you will be prompted to use AI FTP Detection (regardless of when you last used it). AI FTP Detection recognizes this as a sign that you’ve had significant improvement since your last FTP change, so it will make this happen to bring you back into a well-calibrated spot with your training.

If you are in the Specialty Phase, you will get a suggestion to bump your FTP by 2%. This will keep your training focused on extending time in zone, increasing repeatability, or whatever other goal the Specialty Phase has for you, while also avoiding any big changes in your training leading into your goal event.

If you fail a Level 2 workout of any zone, you will get a suggestion to drop your FTP by 2%. Based on learnings from our data, if you find yourself in this situation, this change will make you 38% more likely to pass your next workout.

Whenever you get any of the prompts described above, you are welcome to accept or reject the suggestions, so you will have the opportunity to use this, but you won’t be obligated.

Remind Me Later feature

Sometimes you may not want to accept a result from AI FTP Detection on a specific day, and the new remind me later feature makes it easy to do that while still getting to use it when you want in the future.

If you select the “Remind Me Later” option, you have the option of being reminded after your next workout, in 1 week, or in 2 weeks. No matter which option you select, you’ll see how long until your next AI FTP Detection after every workout.


Thanks for all involved in shipping these updates! AI FTP Detection is hugely popular and helps tons of athletes get faster, and we’ll continue improving it! 🙂
