The short answer
You run on their entry: the bib, the insurance and the results stay in their name. Many rules punish it with disqualification or by voiding the bib, and some ban the person who passed it on from entering for 4 years and, in certain races, the buyer too.
Insurance and results
With an official transfer, the bib ends up in the runner's name, with their insurance and their result. Without it, they stay in the name of whoever signed up. The Zubiri Pamplona Half Marathon rules, for example, require you to run with a bib in your own name: otherwise the insurance doesn't cover you and your time doesn't count.
The penalties
Of the 22 races in our report, 8 punish selling outside the official process with a 4-year entry ban.
- Disqualification: the Benidorm Half disqualifies anyone who passes on their bib outside the official transfer, and Penyagolosa Trails also bans them from future editions.
- Voided bib: the Murcia Marathon voids a bib passed on without the organiser knowing.
- 4-year entry ban: the Valencia Marathon and Half Marathon or the Zurich Barcelona Marathon. At the Barcelona Half Marathon and the León Half Marathon, the buyer is banned too.
What you can do
Make the change through the official process before its deadline: every Pasadorsal guide explains how and until when. If your race doesn't allow it, there's no safe way to run on that bib.
