The short answer
You sign up once the race sells out and, if someone drops out, the organiser offers their place to people on the list, following its own rules. You register and pay on its website. The Valencia Marathon, the Seville Half Marathon and the Zurich Seville Marathon, for example, have one.
How it works
Each organiser sets its own rules. For the 2026 Córdoba Half Marathon, the list is on its entry platform, places from drop-outs and unused invitations go in order of sign-up and, if you get one, you receive a voucher by email.
Sometimes a place from the list costs more than the last price tier: €100 versus €80 at the 2026 Valencia Half Marathon.
Races where we've seen one
- Valencia Marathon and Valencia Half Marathon: ballot bibs that are given up go to it.
- Seville Half Marathon 2026, at €50, and Zurich Seville Marathon 2027: both are non-transferable.
- Santa Pola Half Marathon 2027: at €45, once all 7,000 places are taken.
- Córdoba Half Marathon 2026, on its entry platform.
The official waiting list with Pasadorsal
An organiser can turn its race's Pasadorsal queue into its official waiting list. When a place frees up, they publish it with a single-use entry code or link and it's offered straight away, in turns, first come first served. Joining is free, and you register and pay on the organiser's platform. If your race has one, its guide says so.
