1–5 per dimension by the published rubric. Each score links to its evidence. Blank means no public evidence yet.

DimensionScoreEvidence
Plan quality4Seven power zones, Base/Build/Specialty periodization, per-zone Progression Levels, AI FTP detection and a fatigue model are documented; the exact formulas are not published and forum users report implausible FTP jumps. evidence checked 2026-10-13
Adaptation4Forum users confirm adaptations after completed workouts, surveys and outside rides, with Red Light Green Light turning hard days into endurance or rest; the support overview states only power data is used, so no HRV/sleep input. evidence checked 2026-10-13
Workout feedback3Power targets per interval execute on trainer or head unit (DC Rainmaker 2019); after each ride the app updates Progression Levels and asks a survey with a follow-up when targets were missed, but there is no narrative debrief. evidence checked 2026-10-13
Coaching relationship1No conversational coach in the product; the Jan 2026 TrainerRoad AI launch thread includes a chapter 'Why TrainerRoad AI Isn't Just a Chatbot or LLM' and users link their data to ChatGPT as a workaround. evidence checked 2026-10-13
Transparency3Method is documented in blog, podcast and support pages and adaptations are shown for acceptance, but users in the launch thread often did not understand why their FTP changed. evidence checked 2026-10-13
Value for money3USD 209.99/year with all features included; the independent review rates price 2/5 but calls the plans effective for self-motivated riders. evidence checked 2026-10-13
Athlete sentiment3Mixed: Slowtwitch thread is optimistic but skeptical, TrainerRoad forum threads on RLGL and the 2026 AI update split between praise and complaints about FTP swings; a Substack long-term user calls adaptive training spot-on. evidence checked 2026-10-13
