⏵ WATCH + DEVICE

Wear what you already wear.

Summit Line pulls straight from your connected watch account — Garmin, Coros, and Suunto all sync in automatically. There's nothing to install on the watch itself.

⏵ THE DATA LOOP

YOUR WATCH → SUMMIT LINE

Two steps, one of which is already automatic for anyone running with a watch in 2026.
  1. 01
    YOUR WATCH RECORDS

    Garmin Forerunner 965, COROS Apex 2 Pro, Suunto Race — any Garmin, Coros, or Suunto you already run with. Distance, elevation, heart rate, cadence, GPS track.

  2. 02
    YOUR WATCH SYNCS TO ITS APP

    You already do this. Your run lands in Garmin Connect, the COROS app, or Suunto the moment you finish — automatic if you've ever set the watch up. Summit Line never touches your watch directly; your connected account is the source of truth.

  3. 03
    SUMMIT LINE READS FROM YOUR ACCOUNT

    The first time you connect, we pull your last 365 days (cap: 200 activities). After that we sync within 60 seconds of every new run via your watch service. No polling, no draining your battery.

⏵ POWER USERS

COURSE FILES BACK TO YOUR WATCH

We export your race course as a GPX you can push to your watch via Garmin Connect or COROS Pace Pro. Use the Summit Line course-aware pace projection to set per-segment target paces, then export and ride your watch off the course profile on race day.

DROP-BAG SHEETS

Summit Line generates one printable A4/Letter sheet per drop bag. Includes contents checklist, crew roster, tasks, cutoff time + wall-clock arrival window, plus the runner's name + race name in big legible type. Pin to the bag, hand to your crew chief.

WHAT WE DON'T DO

So you can decide if Summit Line fits your workflow before connecting.
