Knickerbocker Canyon Trail Run

Knickerbocker Canyon Trail Run takes place in Auburn, California, on March 27, 2027, with four trail distances. The 35K (21.7 miles) and the half marathon (13.1 miles) start together at 8:30 AM, the 10K follows at 9:00 AM, and the 5K goes off at 9:15 AM.

Trail racing changes how you read your splits, so plan on effort rather than pace: climbs cost time you will not always get back on the descents, and a mile on singletrack rarely matches a mile on the road. The 5K and 10K suit runners trying trail for the first time, while the half marathon is a natural step up for someone with road racing behind them. The 35K sits closest to ultra territory and asks for long weekend runs on similar ground, practice eating while moving, and shoes you have already tested on dirt.
