The Barn Burner Run course will offer up a variety of challenging terrain.  You’ll be running high through the sprawling Ponderosa Pines in the Kaibab and Coconino National Forest on your way to the finish line. 

*UPDATE 9/18/2021*  – 10k run course that has been modified – there were unpassable roads that were not noted by USFS when they originally approved our courses.  The 10k (and last 6 miles of the 50k) will be on an out and back course.

50K Course: Our 50k course consists of two off-road loops, starting out with a big 25 mile lap before returning to the start/finish to head out for the remaining 6 miles along the 10k course. You’ll navigate forest service roads, singletrack and punchy climbs throughout the day. Bring your lungs, you’ll be topping out at over 8,000’ elevation!

  • 50k / 31 Miles
  • Lowest Elevation:  7,224′
  • Highest Elevation:  8,106′
  • Elevation Gain:  2,473′
  • Steepest Uphill grade +15.6% at 7.94 miles 
  • Longest Uphill 1.96 miles at 13.59 miles

(*Update 9/18/2021*) 10k Course: The 10k course covers the final loop of the longer course, undulating through the pine trees, twisting and turning through the woods along a scenic and adventurous 6 mile out and back course. Hovering at about 7,200’ elevation, you’re sure to put those lungs and legs to the test. 

  • ~10k /  6 miles
  • Lowest Elevation:  7,913′
  • Highest Elevation:  7,998′
  • Elevation Gain:  282′
  • Steepest Uphill grade +5.6% at 0.22 miles 
  • Longest Uphill 0.78 miles at 1.29 miles

Only the 50K is a LT100 Run qualifier.  Only athletes that are 18+ can accept the qualifier coin to race the following year at the LT100. An athlete that is 17 at the 2021 Barn Burner 50K Run can accept the coin if they will be 18 by August 20th, 2022. Each Leadville Qualifying Series race provides 25-100 qualifying slots to the Leadville Trail 100 Run presented by La Sportiva, based on the total number of registered racers at each qualifier event. Half of the qualifying spots will be allocated based on the top age-group performances and half will be drawn among riders who have finished the qualifier race within the allocated cut-off time.

Qualifying slots will be distributed at the Awards Ceremony. Qualifying slot winners MUST BE PRESENT, as the roll-down qualifiers rule will be in effect at each event. All qualifier slots will be awarded and redeemed on race day. You must pay your entry to the LT100 Run within the three days after the event. You will have the option to register for the current year or the following year’s LT100 Run and must decide when accepting your qualification slot. All entries into the LT100 Run are non-transferable.

Intentional littering on the course will be grounds for disqualification. The course travels past many historic sites and through areas of exceptional beauty. Help us keep them pristine. We will have recycling bins onsite.

Leave no trace.

From the very beginning, volunteers have made the Barn Burner possible. We truly appreciate all that our great volunteers do to make our races run smoothly and to make the racers’ experience unforgettable.

If you are going to be in town for the Barn Burner, we would love for you to join the family and pitch in. Thanks in advance for your help — we couldn’t do it without you!
