North Fork 50 Mile/50K Trail Race 
June 28, 2014  7:00 a.m.
Pine Valley Ranch Park, Pine, CO - in the mountains 40 miles southwest of Denver

A benefit for the North Fork Volunteer Fire Department and The Evergreen Chorale

The 2014 race is full!  No more entries are being accepted.  Entries are non-refundable and non-transferable, and there is no wait list.  Please consider volunteering to help at the race (see below).  Registration for 2015 will open in mid-January.  

The North Fork Trail Race is run entirely on trails in the Buffalo Creek Recreation Area in the Pike National Forest, starting and finishing along the rushing North Fork of the South Platte River in Pine Valley Ranch Park in Pine, Colorado, in the mountains 40 miles southwest of Denver.   The course is very hilly and it is challenging for those who are not experienced mountain trail runners, but speedsters who are used to altitude find the course quite runable.  The friendly aid stations, beautiful scenery and generous time limits make North Fork an excellent choice for a first trail ultramarathon.  Runners get unique finisher awards, a high quality gender specific tech shirt, and a fabulous post-race barbecue.  Come join us on June 28, 2014!! 

The North Fork Volunteer Fire Department, the primary beneficiary of the proceeds from the race, protects the area where the race is run.  They have helped to battle a number of fires in recent years that have changed the landscape, opening up broad vistas of the high country, as you see in the photo above, and giving birth to new growth. 

You will run through some of the burn areas, but most of the course is in pristine forests of ponderosa and lodgepole pines dotted with fields of wildflowers.  Be sure to check out the photo gallery by clicking "photos" in the far upper lefthand corner of this page.  The course is 100% trails, mostly single track and some double track, with mostly good footing, at altitude ranging from 6,700 to 8,100 feet for the 50K and up to 8,400 feet for the 50 Mile.  Elevation gain is about  4,650 feet for 50K and 7,350 feet for 50 miles.

Part of the race proceeds will also go to the Evergreen Chorale, members of which will be volunteering on race day.  Learn about the Chorale at .  


It takes a lot of help to make this race happen for the runners and race beneficiaries.  Runners are needed to help mark the course the day before the race and to sweep the course on race day.  Non-running volunteers are needed at aid stations out on the course and at Pine Valley.  The "early shift" at Pine Valley begins at 5:30 a.m. with pre-race check-in, then setting up the finish area and barbecue, and then working the finish line and barbecue starting at about 11:00 a.m.  The barbecue continues until 8 p.m. and the finish line until 9 p.m. when everything needs to be taken down and packed up.  Pine Valley volunteers can help early, mid-day or the "late shift."  If you aren't running this year, please come out and volunteer!  If you or someone you know wants to help, email the race director at to sign up, or you can sign up directly on SignupGenius.


Informal training runs will be held on the course on April 26 (snow conditions permitting), May 10 and June 7.  The April 26 run will be at 8:00 a.m. at the Shinglemill aid station location.  All the details are on the instruction sheet below. The course will not be marked (you will have a map and directions), and aid will be limited.  By doing all 3 runs, you can see the entire 50 Mile course.  The April and June runs will show you the entire 50K.  Capacity may be limited due to limited parking.  Registered race entrants may bring guests who are not entered in the race.  Email the race director at if you would like to participate.  Print the instructions and map below if you are participating.
