First, the 25K will have its own day, March 9. If you want to sign up for the 25K you will need to go to . If you plan on signing up for the 50K, 50 mile, or 100 mile, this is the place to go. If you want to sign up for both the 25K and one of the other distances, go to the 25K registration page and there will be an option to do that along with special pricing if you sign up for two races. Such a deal!.

Start Times
Since everyone always asks when the races start, here are the times:
100 Mile – 10am Friday, March 22
50 Mile – 6am Saturday March 23
50K – 8am Saturday March 23

There WILL NOT be an early start option for the 100 mile. There is an early start option for the 50 mile, it is to start at 10am with the 100 mile runners. Please sign up for this ONLY if you have serious doubts about your ability to go 50 miles in 12.5 hours.

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.
There are no transfers 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.
I DO NOT allow race entries to be sold or transferred to anyone. 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.

All of the courses will remain the same. No changes at all.
The 50K will follow the same format as always, two trips around White Rock and Split Rock trails. All you 50K runners make sure you turn around at the White Rock aid station at the trailhead at the fence. Do Not go down the dirt road at all and don’t cut it short.

The 50 mile course will be the same as usual. Maps of the various courses are on the race website,

Other Stuff
If you need any other information, just go to the race website. It has lots of pretty pictures and cool words, plus a fair amount of race information.
