2537m Trail - Ultra

Adaptive trail and ultra coaching built from your runs. Plan smarter, fuel with confidence, track recovery, and turn any GPX course into a personal race strategy.

2537M Trail - Ultra is adaptive training intelligence for trail and ultra runners.

It brings your training, recovery, fuelling, strength work and race preparation together, then helps you decide what to do next using evidence from your own running.

A PLAN THAT LEARNS FROM YOUR RUNNING

Build towards your trail or ultra goal with a living plan that responds to completed and missed sessions, recovery, training load, body signals and the demands of your race.

When your completed workout differs from the planned stimulus, 2537M can recognise what you actually achieved and reassess the remaining week. Proposed plan changes require your approval before they are applied.

PLAN YOUR RACE FROM THE COURSE

Upload a GPX course to build a race strategy around the actual distance, elevation and course order.

Review every segment from start to finish, including repeated aid-station visits, estimated arrival times, ascent, descent, average heart-rate guidance, carbohydrates, fluid and sodium. Export the segment plan as a CSV for your crew and race preparation.

Race estimates use relevant long runs, hard sessions, terrain, pace, heart rate and climbing evidence rather than relying only on a race title or target time.

TRAIN FOR YOUR RACE CONDITIONS

Prepare for more than distance. 2537M considers elevation, terrain, technical trails, surface, weather and other race demands, helping you practise in conditions that matter.

COMPARE THE RUNS THAT MATTER

Compare complete routes and overlapping sections within longer runs.

2537M can identify comparable uphill, downhill and level-ground sections, pace and heart-rate behaviour, vertical speed, repeated routes and structured workouts. The strongest evidence is prioritised while recovery concerns and gait-changing body signals take precedence over optimistic performance conclusions.

UNDERSTAND THE WHOLE RUN

Debrief each run with more than pace and distance. Record purpose, whole-session effort, finish reserve, terrain, conditions, fuelling, hydration, gastrointestinal response, pain and other details that explain how the run actually went.

Detected pace and heart-rate behaviour help identify the completed physiological stimulus, even when an activity title does not accurately describe the workout.

PRACTISE YOUR FUELLING

Develop carbohydrate, hydration and sodium targets from successful, recorded practice.

2537M focuses on runs where intake was recorded, rather than treating zero or unrecorded intake as evidence of limited tolerance. Race guidance considers your strongest supported intake, long-run experience, sweat information and expected conditions.

TRACK RECOVERY AND BODY SIGNALS

Bring sleep, daily activity, recovery and workout information into one view. Add a short runner report for freshness, soreness, sleep, life stress and motivation.

Use the interactive body chart to record the location, severity and details of pain or discomfort over time. Recovery and safety signals can influence training recommendations.

MANAGE YOUR SHOES

Add shoes from the 2537M catalogue or create a custom shoe. Track distance in kilometres or miles, retire worn shoes and record whether a shoe may be connected with pain or recurring issues.

Race strategy can identify a primary shoe and help you consider a more cushioned, stable or accommodating backup option for later stages.

CONNECT YOUR RUNNING DATA

Bring together information from Apple Health, COROS and Strava, depending on the services you connect. Heart-rate zones use the best available source from your recording device, primary watch or connected platform.

2537M is built for runners preparing to finish well, not simply start fast.
