Triathlon, Strength AI level: Model-driven adaptive Adaptive plan human coach in the loop USD 14.99/mo pushes workouts to 2 devices
TriDot generates swim, bike and run sessions from an athlete's training data and adjusts upcoming sessions after each synced workout, normalising for environment (heat, humidity, elevation). It imports activities from Garmin, Apple Watch, COROS, Wahoo, Fitbit and Strava, sends sessions to Garmin devices and Zwift, and includes an in-app assistant for questions about completed workouts. Pricing is a monthly subscription in four tiers from USD 14.99 (one sprint or Olympic race) to USD 249 with a dedicated coach, with a 14-day trial.
Model-driven adaptive. A physiological or statistical model (fitness-fatigue, critical power, ML on the athlete's history) decides load and session type without a conversation. source

Scores
1–5 per dimension by the published rubric. Each score links to its evidence. Blank means no public evidence yet.
| Dimension | Score | Evidence |
|---|---|---|
| Plan quality | 3 | Vendor names individual training zones, Normalized/Residual Training Stress and environmental normalisation but publishes no mechanism or references; Slowtwitch users note the 3.2X claims and 'research' are unpublished (forum.slowtwitch.com/t/any-tridot-users/794702). evidence checked 2026-10-13 |
| Adaptation | 3 | Slowtwitch users report the plan adjusts to their results and zones from their own data and that single sessions can be moved; vendor says sessions adapt after a rough week. No documented use of sleep, HRV or wellness inputs. evidence checked 2026-10-13 |
| Workout feedback | 3 | Vendor: sessions push to Garmin and Zwift with environment-adjusted intensities, and a TrainX score rates how well the prescribed session was executed with 'clear insights after every session'. No independent review describes the post-session debrief; vendor-only evidence. evidence checked 2026-10-13 |
| Coaching relationship | 2 | Vendor describes an in-app assistant that answers questions about completed workouts (compare intervals, best 20-min effort). It is not stated to change the plan on request; vendor-only evidence. evidence checked 2026-10-13 |
| Transparency | 2 | Users say each workout targets a specific adaptation, but the FitLogic method page only names its components; critics in the 2020-22 thread call the explanations 'technobabble with no real substance'. evidence checked 2026-10-13 |
| Value for money | 2 | USD 14.99/mo tier is limited to one sprint/Olympic race; longer distances and RaceX need USD 39/mo, unlimited races USD 99/mo. A Slowtwitch user found TrainerRoad's annual plan better value. evidence checked 2026-10-13 |
| Athlete sentiment | 3 | Mixed: Slowtwitch thread split between ambassadors/users praising results and sceptics; Trustpilot 4.0/5 (108 reviews) with recurring billing complaints (trustpilot.com/review/tridot.com); App Store 4.7/5 (263 ratings). evidence checked 2026-10-13 |
