North Fork 50 Mile/50K

18050 South Buffalo Creek Road

Buffalo Creek, CO 50 Miler, 50K

Registration closes: Thu, Jun 4 @ 11:59PM


UPDATE: April 3, 2020

Per the CDC and White House's recommendations of extending the mitigation strategy of social distancing and shelter in place through April 30, we are we are still looking good to continue forward with our original race date of June 6. I am continuing to to stay in touch with the USFS as things progress, and if it looks necessary for us to postpone to a makeup date we'll make a decision as quickly as possible. If we do need to postpone, ideally we will try to hold the race as soon as it is safe to hold group events (fingers crossed for late June/early July, so only a short postponement). We are also working on new safety procedures for our runners and volunteers at the start/finish area and aid stations.

Additionally please note that the race field is full. I've received numerous inquiries from runners who would like to get in, but per our permit with the USFS that is just not an option at this time. I realize that many other events have already cancelled, and many runners are now looking for other races to run. Should things change with this and we can accept more runners, I will be sure to notify everyone. If you missed out on getting signed up for this year's North Fork 50, you can still get in on the other races in The Bear Chase Race Series.

Please stay engaged with us through our Facebook page, and we’ll continue to post updates over the upcoming weeks. Stay healthy, please continue to train smart by running solo and practicing social distancing, and we'll see you all on the trails soon!

North Fork 50

The North Fork 50 Mile/50K is 100% trails, mainly single track and some double track, in the beautiful Buffalo Creek Recreation Area in the Pike National Forest, starting and finishing along lovely Buffalo Creek in Buffalo Creek, Colorado, in the mountains about 50 miles southwest of Denver.  This is a pure ultra, a very special and unique race, deliberately kept small so each runner gets personal attention. There are no non-ultra distances and no crowds on the beautiful trails. Celebrate your accomplishment at the fabulous post-race barbecue with your choice grilled to order and beer from our great sponsor Avery Brewing. Proceeds of the race benefit the North Fork Volunteer Fire Department, which protects this scenic area and for whom the race is named,, and Conifer's StageDoor Theatre.

The course is one loop for 50K, plus an out-and-back section in the 50 Mile.  The course is mostly in lovely pine forest, but it also includes parts of the areas burned in the 1996 Buffalo Creek fire, which the North Fork Fire Department helped to fight. The fire created a stark and fascinating landscape and opened up breathtaking views of the high mountains and unique rock formations. The altitude is 6,700 to 8,100 feet in the 50K and 6,700 to 8,600 feet in the 50 Mile. The 50K has about 3,800 feet of climb, and the 50 Mile about 6,500. Although the course is very challenging for those who do not regularly run mountain trails, speedsters used to altitude will find the course quite runable. And the friendly aid stations, beautiful scenery and liberal time cutoffs make North Fork an excellent choice for a first trail ultramarathon. Complete race, course and lodging information can be found on the race website (click the website link above).


275 entries will be accepted in total for both distances, and there will be no wait list. ENTRIES ARE NON-REFUNDABLE, NON-TRANSFERABLE AND CANNOT BE ROLLED OVER TO THE FOLLOWING YEAR. Please see the Registration page of the race website (link above) for complete details of this policy.
