Switching Races Policy

You may switch from your current Yuengling Shamrock Marathon Weekend race to one of our other Shamrock Marathon Weekend races distances. If you a switching to a shorter distance, you will not receive a refund if there is a lower registration fee.  If you are switching from the 8K to the Half Marathon or Full Marathon or from a single race to the challenge, you must pay the difference in race fee from what you initially paid for your original category to your new race category at the time of the switch.  Switching races will no longer be available once a race distance has sold out.

The deadline to switch categories is Thursday, March 13, 2025.

Bib Transfer Policy

You may transfer your race entry to another individual for an additional $25 transfer fee. Race entries must be officially transferred. Allowing another individual to run with your race bib without transferring your race entry is grounds for disqualification from the results and banning from all future J&A Racing events.

The deadline to transfer your race bib is Thursday, March 13, 2025.
