This page is about what TriPeak decided, not about what anybody else does. Other tools change, and a comparison written today would be wrong by spring. Decisions are more durable, and they are the honest thing to be judged on.
TriPeak does not call a language model. It runs a Model Context Protocol server and lets the assistant you already pay for — Claude, ChatGPT, Gemini CLI, VS Code, Cursor — read and write the real plan.
The practical difference is that the intelligence improves without us shipping anything, you are not paying twice for AI, and there is no prompt of ours between you and the model. The cost is that you need an assistant: there is no chat box inside the product.
Sessions an assistant creates for a coached athlete arrive invisible to the athlete and excluded from the load model until the coach accepts them. This is deliberate friction. A tool that lets a model quietly rewrite somebody's training week is a tool that will eventually do it badly on a week that mattered.
Strava's API terms allow an application to show athletes their own data. They do not allow showing an athlete's data to their coach, which is the entire job here. Rather than build an integration that works for self-coached athletes and breaks the moment a coach is involved, there is none.
Garmin and Wahoo connect directly. Everything else works by dropping a .fit, .tcx or .gpx file onto the plan, which every watch on the market can export and which depends on no integration at all.
Plans differ only in how many athletes they cover. There is no tier where execution grading or the AI connection is withheld to make a more expensive tier look better. 30 days free, no credit card, monthly, cancel any time.
Six training philosophies ship with the product, each with the research behind it cited and each with a plain statement of how it fails and who it does not suit. A tool that recommends one approach and never says what it costs you is selling a house style as a fact.
TriPeak is triathlon coaching software for coaches and self-coached athletes: structured sessions scored in TSS, fitness and form tracking, Garmin sync with execution grading, and an MCP server so Claude or ChatGPT works with the real plan.
