The Race

​​And the 2019 race is now in the books!  Results are below and can also can be found on UltraSignup.  It was a fabulous weather day, and everything went smoothly at the new start/finish at Buffalo Creek.  

Results are below and can also can be found on UltraSignup.  

And several new course and age group records were set.  You can see them on the Records/Results page.

​Next year's race will be Saturday, June 6, 2020.  Put it on your calendar!  The 2019 race info is still here on this website, and we anticipate that 2020's will be very similar.  We will update for 2020 over the coming months.

From Janice, the Race Director:  It is with very mixed feelings that I am retiring as R.D.  I love the race I created and it has been a joy to watch it grow over the years.  But 10 years of managing the race has been enough as my husband and I have been enjoying our retirement and doing more traveling.  Information will be coming soon about the wonderful new race management for next year.  Stay tuned!

50 Mile/50K

June 6, 2020, 7:00 a.m. - Buffalo Creek, Colorado​​

The 50 Mile and 50K are 100% dirt, mostly single track trail and some double track and dirt road, in the beautiful Buffalo Creek Recreation Area in the Pike National Forest, starting and finishing along lovely Buffalo Creek at the Community Hall in Buffalo Creek, Colorado. The Community Hall belongs to the Buffalo Park Improvement Association (BPIA or, as the locals call it, "Bippy")--so our start/finish is nicknamed Bippy. The elevation ranges from 6,700 feet to 8,100 feet in the 50K and to just over 8,500 feet in the 50 Mile.  With 3,800 feet of climb in the 50K and 6,600 feet of climb in the 50 Mile, the race is very challenging for those not used to mountain trail races, yet speedsters who are used to altitude will find the course quite runnable.

The race benefits the North Fork Volunteer Fire Department, which protects the area where the race is run and for whom the race is named.  They have helped to battle a number of wildfires in the area over the years that have changed the landscape, opening broad vistas of the high country and making way for new growth. You will run through some of the burn areas, but most of the course is in pristine pine and aspen forest. The beautiful scenery, friendly aid stations and generous time cutoffs make North Fork an excellent choice for first-time ultramarathoners as well as veterans.  Runners get high quality tech T-shirts, unique finisher awards, a fabulous post-race barbecue and the satisfaction of a job well done.

All the course and race information can be found under the Race Info tab above.  If you have questions, feel free to email the race director at or call 303-903-3533.
