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
- Every run counts, indoor or out.
- Distance tracked in miles (switch to km when you create it).
- 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.
