Race Distance Changes

BIB TRANSFERS
Allowing a non-registered runner to use your bib is NOT PERMITTED
This race typically sells out quickly. It is unfair to give your race bib to someone else. There will be many people who were not able to register before the sell out and this would not be fair to all. Additionally, runners will receive detailed information from us days leading up to the event with updated safety requirements. Non-registered runners will not have signed the waiver and will not have receive communication from us.
