Race Information

Runners will run on the historic Western States trail, out to No Hands Bridge then tackle one of the toughest climbs in the area, and training grounds for top runners, the dreaded K2 training hill. The 5K and 10K courses run killer single-track trails along the banks and canyons of the American River. The Half Marathon and 35K cross No Hands Bridge, up K2 then towards Cool, CA. If you’re in it for the long haul, you will head back down to the River the ascend the the long series of switchbacks, known as the “Dam Hill”. This beautiful and varying course is sure to challenge and inspire.

Knickerbocker Canyon Trail Run


  • KeenanB

    does anyone know the elevation gain in the half?

  • Tim Stahler

    The half will have approximately 1,450′ of climb. Elevation profiles are being posted now!

  • Slowdancers

    Do you have finisher medals or only medals for top 3 age group winners?

  • Peter Fain

    Had a good time in the race. Wasnt really ideal for a first race back from an injury but it was fun none the less. The descent to no hands bridge was practically like running in a stream bed, as was many other portions of the course. The climb was fantastic. Enjoyed some turkey specatating near the top, and the home stretch on the olmstead loop was a muddy jaunt. Again, a good time.

  • Celia Dean

    Just coming off foot surgery looking at the 5k does it go up K2

    • Tim Stahler

      Hi, Celia. We updated all the maps and elevation charts with the 5K course. It does not go up K2… Compared to the other events at Knickerbocker Canyon, it is relatively flat. It will be a little longer than 5K… right around 3.3 miles.

  • Cheryl Kurowski

    looking forward to this run! I’m interested in the 1/2 marathon distance. Wondering if it’s the same route as the Fourmidable 1/2 that was just yesterday?

    • Tim Stahler

      I’m not familiar with the Fourmidable route, but the half is the same course as we used last year. Heading out from Cool Firehouse to No Hands, up Training Hill to a portion of Olmstead Loop. From there you’ll go down Coffer Dam Trail to the river and back up the Auburn-Cool Trail (Dam Hill) then on to the Firehouse. A fun, challenging route! -Tim

  • Celia Dean

    I can’t believe I talked my husband into doing the 5k… He has never done a race before…so now instead of running this I will be run/walking with him….
