UPDATE AS OF 1/23/2023: Lake Chabot has received some major damage from the storms starting New Years Eve through the first few weeks of January. We are working to reschedule the event as at Lake Chabot AND finding a new venue for February 18th. More updates to come.Park information: Lake Chabot
Lake Chabot Regional Park was established in the 1960s after the reservoir had been closed to recreational use for 91 years. Today, the lake remains as an emergency water supply and is open to fishers and boaters, as it is filled with trout, catfish, bass, crappie, and other fish.
With eucalyptus forests, grassy meadows, lakeside paths, and hill top vistas, Lake Chabot offers over 20 miles of hiking trails, which connect to the additional 70 miles of trails in adjoining Anthony Chabot Regional Park making it a spectacular place to run and also very accessible.
This is one of our typically faster races with less elevation and some paved sections. The course is designed for those who are looking to PR and those who are less competitive and/or just embarking on trail racing.

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, 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, bananas, watermelon, and tangerines. Aid stations are also equipped with general first aid items, including Salt-Stick tablets, but no anti-inflammatory medicine.
Tailwind is mixed so that it contains 180 – 200 calories per 20 fluid ounces.
As distances between aid station vary, we strongly encourage all runners to carry at least one 20oz bottle during their run.
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.

ITR Refund Policy:
Local time: 11:46 PM
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.
