Why This Works

  • It’s a stretch — not a sprint. 100 miles forces a schedule, not heroics.
  • Splits cleanly into 4–5 runs a week. Miss a day, catch up on the next.
  • Auto-sync means every run counts the moment you stop your watch.

The Rules

  1. Every run counts, indoor or out.
  2. Distance tracked in miles (switch to km when you create it).
  3. Sync from Strava or Garmin, or log manually.

How Meryus Tracks It

When you start this challenge, Meryus creates a shared page with a live chart, member leaderboard, and a join code. Every activity you record on Strava or Garmin syncs automatically — no manual entry, no spreadsheets.

Share the join code with anyone. They land on the challenge, hit Join, and their progress appears on the same chart. That's the whole product.
