Check the record.

Every WALK50K certificate carries a verification ID. Enter it to confirm the result is genuine.

The code is the #ID printed at the bottom of any certificate, or encoded in its QR. Six characters, digits and A–F. You can also paste a full verification link.

• Check for look-alikes — the code only uses 0–9 and A–F (a “0” is a zero).
• Only completed challenges have a record. A DNF never verifies.
