M312 PROOF Edition
The island’s longest day. Finish the loop and earn your place in the record.
The challenge
Some rides are training. Some rides are a statement.
M312 — PROOF Edition is built for one effort only: the full 312-kilometer loop in a single day. No shortcuts. No split attempts. No softened version of the story.
This is the kind of challenge that stays with you long after the finish line.
The mission
Complete 312 km in one ride on event day.
Rules
- Challenge date: April 25, 2026
- The full effort must happen in one single activity
- Outdoor ride only
- Joined athletes will have qualifying PROOF posts counted automatically
- Completion comes first; ranking then reflects who finished and how they got there
The standard
Three hundred and twelve kilometers does not care how motivated you felt at breakfast. It asks one question: can you keep going when the day gets longer than your plan?
If you finish, it counts. If you post it, it lives.
No noise. No padding. Just PROOF.
Finish what you start.
No excuses. Just Proof.
This is not a segment chase. PROOF ranks finishers first, then rewards how they got there. Completion comes before noise.
