RestOrTrain vs Claude with the Strava MCP connector

Strava already supplies Claude with calculated figures. Claude can also read load or FTP from screenshots, or use uploaded files. It does not need to recalculate those supplied numbers. Additional calculations depend on its analysis for that question and can produce different results between answers.

RestOrTrain calculates every number it can without AI, including FTP estimated from your power curve. It applies the same calculations to each synced ride and answers from those results, leaving less room for calculation errors.

RestOrTrain's tests of language models in general found a conservative bias: training weeks that were too light and key sessions that were too short. It is tuned for endurance training to avoid that bias.

Ask where your power faded on yesterday's climb and what to change in training. RestOrTrain uses your power profile and recovery data to give a concise, concrete recommendation.

Its answer draws on your training history, including the strengths and weaknesses it has learned over time. Ride notes and past conversations matter too. It weighs those alongside sleep, HRV, resting heart rate, training load and the workouts on your calendar.

What you tell it after a workout informs later decisions. Facts remembered from chats are visible in the Memory list on the Profile tab.

RestOrTrain divides your season into dated phases toward your goal, each with a range of weekly hours and a reason. It creates the individual workouts and puts them on the calendar. You can request another structure, such as "5 x 3 minutes at 350 W", or adjust a session in the chat.

You approve changes it proposes. When you ask it to revise the plan because your race moved, it does so immediately and sends the updated workouts to your devices.

Rides sync from Garmin, COROS, Wahoo, Hammerhead, Intervals.icu, Zwift and Rouvy. A ride recorded on two devices is kept once.

Planned workouts go to Garmin Edge and compatible Garmin watches, Wahoo ELEMNT, Hammerhead Karoo, COROS, Zwift, Rouvy and Intervals.icu. With an iPhone, planned rides and runs also go to Apple Watch.

It also builds structured running and swimming workouts. You can combine running and cycling or follow one triathlon plan. Gym sessions have exercises and sets written out.

Ask to chart your threshold power across a training block. RestOrTrain draws a bar or line chart in the reply from your computed data, with nothing to upload. Your power bests from 5 seconds to 60 minutes also have percentiles against other riders and an estimated racing category.

On iOS and Android, the indoor player runs your workout on a Bluetooth smart trainer that supports FTMS. ERG adjusts resistance to match each step's power target. A heart-rate strap is optional. You can turn ERG off or change intensity by 1% per tap, from 50% to 150%. The workout continues with your phone locked.
