Participants of this race will run along the historic Western States trail, out to “No Hands Bridge”, then tackle one of the toughest climbs in the area: the dreaded K2 training hill. The 5K and 10K courses include 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”. The course is varied and far from monotonous, allowing runners to push past discomfort and focus on what’s enjoyable.

Aid Stations

Inside Trail Racing aid stations are replete with an optimal variety of glycogen-replenishing, electrolyte-replacing products. The following is a list of some of the foods and beverages each aid station may provide: Gu Energy gels and chews, all-natural nutrition bars from Larabar, trail mix, pretzels, potato chips, Oreo cookies, Pop Tarts, boiled potatoes with salt, Coke, Mountain Dew, Ginger Ale, water, Tailwind Endurance Fuel, PB&J sandwiches, M&M’s, Mike & Ike’s, salt tablets, and tangerines. Aid stations are also equipped with general first aid items but no anti-inflammatory medicine. As distances between aid station vary, we strongly encourage all runners to carry at least one 20oz bottle during their run.

Tailwind is mixed so that it contains 180 – 200 calories per 20 fluid ounces.


Without the support of enthusiastic and caring volunteers producing our races would not be possible. Volunteers of all ages and abilities help with setup, check-in, aid stations, course marshaling, timing, and post-race food.

Volunteering is a fun, novel way to experience races, play in the outdoors, and spend time with friendly people. All volunteers receive a free race T-shirt, free food, and the ability to earn credit toward a future Inside Trail Racing event, commensurate to the amount of time worked. Five hours of assisting an event results in a free race credit or Inside Trail merchandise.

To volunteer for this year’s event, please submit our online volunteer form.
