TrainerRoad vs phase.fitness
TrainerRoad is built for one sport and goes deep into it. phase.fitness is built for a week that has more than one sport in it. Which one is right depends on what else is in your week.

The short answer
TrainerRoad plans cycling, triathlon and off-road riding, moving you through base, build and specialty phases to race day while its AI picks each workout and adjusts in real time from your history, performance and recovery; it detects FTP without a test and sends workouts to Garmin, Wahoo, Hammerhead or Zwift. phase.fitness plans riding next to strength and bodyweight skills in one periodized program, writes the rides to Intervals.icu and Garmin as a share of your threshold, and rewrites the next phase from the rides and the lifts together.
What TrainerRoad is
A cycling training app whose AI picks and adjusts each workout, for indoor trainers and outdoor riding, with plans for cycling, triathlon and off-road.

When TrainerRoad is the better choice
- Cycling or triathlon is the whole training week, and you ride indoors on a smart trainer.
- You want FTP detected and each workout adjusted ride by ride.
- You ride in Zwift and want the structured workouts there.
When phase.fitness is
- Strength and bodyweight skills are part of the week, not only the bike.
- You plan in Intervals.icu and want the block written to your calendar there.
- You want the strength sessions to land in Hevy, Liftosaur or a Garmin watch.
Where to start in phase.fitness
- Cycling training plan built on power zones and real strength — phase.fitness plans road and gravel cycling as base, build and peak blocks with a recovery week every 3–4, keeps the low intensity genuinely low, and adds squat and hinge strength at 3–5 sets of 4–6 — two sessions in base, one in build, none or one in the peak.
- Cycling and strength training program — Strength for cyclists is not more riding with plates: it is squat and hinge patterns at 3–5 sets of 4–6, placed where they cannot spoil the hardest ride, and it fades from two sessions to one as the riding block hardens. phase.fitness plans both halves in one week.
- Triathlon training plan: three sports and one strength day — phase.fitness plans a triathlon week as an ordering problem: three sports, a recovery budget that does not grow because there are three, and one or two strength days that stay heavy and short instead of becoming a fourth sport.

- phase.fitness for triathletes
- phase.fitness for Intervals.icu users
Questions
Is phase.fitness a TrainerRoad alternative?
For a rider whose week also holds the gym or a second sport, yes: phase.fitness plans them together and orders the week around the hard rides. For a cyclist who wants every ride tuned on a smart trainer, TrainerRoad goes deeper into the bike than phase.fitness does.
Does TrainerRoad plan strength training?
The pages we read in October 2026 do not describe strength sessions as part of a TrainerRoad plan. phase.fitness writes squat and hinge work with single-leg and trunk exercises, two sessions in base and one in build, away from the hardest rides.
What does TrainerRoad cost?
Its site lists $21.99 a month or $209.99 a year, refundable within 30 days, as of October 2026. phase.fitness is $34.90 every three months or $104.70 a year, with no monthly plan.
