Race Information
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 Station Supplies
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, chews, and Stroopwafels, trail mix, pretzels, potato chips, Oreo cookies, Coke, Mountain Dew, Ginger Ale, water, Skratch Labs Sports Hydration Mix, PB&J sandwiches, M&M’s, salt tablets, bananas, watermelon, and tangerines. Aid stations are also equipped with general first aid items, including Salt-Stick tablets, but no anti-inflammatory medicine.
Skratch Labs is 80 calories per serving with minimal sugar (4g per 100 ml) and a ratio of sugar (glucose + fructose) that is optimized for faster absorption, an electrolyte profile that actually matches what is lost in sweat (800 mg sodium, 80 mg potassium, 100 mg calcium, and 80 mg of magnesium per liter)
As distances between aid station vary, we strongly encourage all runners to carry at least one 20oz bottle during their run.

ITR Refund Policy:
Entry fees to our trail runs are non-refundable in all cases, and we do not offer credits, transfers, or deferrals to future races except as described below. Only registered runners can participate in our races, and you cannot exchange your entry with anyone else in any case.
We are happy to issue a credit worth 50% of your original race fee toward a future Inside Trail Racing event if we receive your cancellation at least 3 weeks prior to the race. Credits will expire 1 year after the date issued. There will be no credit provided if a cancellation is made within 3 weeks of the race.
While we understand that last-minute injuries, conflicts, emergencies, deaths, and other unfortunate events affecting registered runners can happen and may impact your plans for participation, we must adhere to our cancellation policy stated above and cannot offer any credits, refunds, transfers, or deferrals in any of these cases.
If the situation does arise where ITR must outright cancel an event for any reason, there will be no refunds. This could include earthquakes, floods, extreme weather, unsafe air quality, pandemics, or any other “Act of God”. ITR at its sole discretion may choose to offer future race credit or deferrals in these force majeure situations, depending on the circumstances and how close to the race date the event was cancelled. We will communicate with all registered runners as soon as possible regarding the cancellation and any pertinent information.
We do not cancel races due to rain or heat. Due to trail work, closures, or for myriad other reasons, permitting agencies may require changes to the publicized courses at any time prior to an event. This is out of our control, and we therefore will not offer refunds, credits, deferrals, or transfers (except as described below) in such a situation. If a race location is changed, but still hosted on the same day, we will automatically transfer the registration over to the new venue, or entrants may choose to run the race remotely and we will mail awards. If a race is postponed all entrants will be transferred to the new date.
