What kind of triathlete
are you when the race
starts cooking?
15 scenarios. 7 race personas. One uncomfortable truth about who you become at km 32.
Pressure does not test fitness. Pressure tests the version of you that appears when the plan dies and only decisions remain. Built for T100 fans, long-course athletes, masters age-groupers, coaches, and anyone who has ever lost three minutes in T1 looking for their visor.
This decoder is educational and reflective, not a validated assessment, not diagnostic, and not a performance predictor. Triathlon training and racing require appropriate preparation, medical clearance when needed, safe conditions, and qualified coaching support.

“I told myself the watch dying was the problem. The watch dying was not the problem. The problem is that I do not actually know what threshold pace feels like.”

This decoder is the triathlon companion to the essay Open Water Is Decision-Making Under Uncertainty, the flagship piece in the Lessons from the Water series on Deep Water. For the song that started this whole project, listen to Every Stroke on Spotify.
This decoder is an educational, reflective tool only. It is not a validated psychometric instrument, not a diagnostic test, not a performance predictor, and not a coaching prescription. Use the result as a prompt for coaching discussion, training reflection, or race-plan review, not as a conclusion about your psychology or future performance. Triathlon training and racing require appropriate preparation, medical clearance when needed, safe conditions, and qualified coaching support. Listen to your body. Stop racing if you experience chest pain, severe dehydration, dizziness, or signs of heat illness.
