A hidden redwood forest lies in the hills just a few miles over the ridge from downtown Oakland. The forest’s peaceful groves give little evidence of the park’s bustling past – in the mid-1800s the area was the scene of extensive logging to supply building materials for the San Francisco Bay Area. The logging era has long since passed, and a stately forest of 150-foot coast redwoods (Sequoia sempervirens) has replaced those cut down.

In addition to a great forest of coast redwoods, the park’s 1,830 acres also contain other evergreens, chaparral, and grasslands. Wildlife within the park includes rare species such as the golden eagle and Alameda striped racer. Deer, raccoons, rabbits, and squirrels are often seen.

ITR Refund Policy:
Entry fees to our trail runs are non-refundable, and we do not offer transfers or deferrals to future races. However, with advanced notice, we are happy to credit part of your entry fee to a future Inside Trail Racing event. A credit worth 50% of your original race fee will be issued if the cancellation is received at least 3 weeks prior to the race. There will be no credits or refunds provided if a cancellation is made within 3 weeks of the race. Only registered runners can participate, and you cannot exchange your entry with another runner. Credits will be available for 1 full year from its issue date.

Only registered runners can participate, and you may not exchange your entry with another individual.

We do not cancel races due to rain or heat. Due to trail work, closures, “Acts of God”, 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 or credits in such a situation. If a race location is changed due to park closures, we will automatically transfer the registration over to the new venue, or entrants may choose to cancel their entry (non-refundable) and we will mail awards.

Hosting a trail running event is an expensive and risky endeavor. All race costs are paid for well in advance of race day, so there is no financial gain to be made if a person does not show up on race day. We want all of our registered runners to show up, run, and have fun. While we understand that injuries, conflicts, emergencies, deaths, and other unfortunate events happen and may impact your plans for participation, we must adhere to our cancellation policies.

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.
