Refund/Transfer/Rollover Policy

We will refund your entry, less the service fee, provided you let us know before the February 1st deadline.
The race does not have to be full.
There are no rollovers for any Buffalo Run Adventures races.
The entry fee you pay is for this year’s race and covers this year’s supplies, fees, insurance, etc.
If you want to transfer to a friend, you MUST do it through this registration page. This is at no cost. Unofficial transfers are not allowed, so don't just sell your friend your bib. This is a liability issue.
If you are out running the race and get hurt and can’t communicate with us, I have no idea who you are, who to contact, etc.
Plus it has the potential to really screw up results. So don't give/sell your buddy your bib.
The best thing to do is to get your refund and have your friend just sign up for the race.

Course

New course descriptions, maps, etc. have been added to the website.
