CONGRATULATIONS RUNNERS!
RACE INFO
The Reservoir Dogs Trail Race is the first trail-running event allowed to completely circumnavigate the Briones Reservoir on the serene–and usually “permit-only”–East Bay Municipal Utility District (EBMUD) trails.Most trail runs are inherently beautiful, but this course offers more rolling open fire roads and boasts a nice progression of quintessentially East Bay environments, along with tree covered single-track and sweeping views of the watershed lands. Briones Reservoir is also one of the few EBMUD properties that has a substantial length of single-track trail. The 10K, Half Marathon and 35K courses are faster than other Inside Trail races because they have less elevation but they are consistent in a design intended to push each runner.
The Start and Finish for all races will be in the San Pablo Reservoir Recreation Area, which has a plethora of outdoor activities for all ages, including: hiking, fishing, kayaking/canoeing and picnicking.

DETAILED COURSE INFO
Printable Course Information
Course Composition
The vast majority of the course will be run on moderately technical dirt trails and fireroads. The course has gently rolling hills the entire way, and fun twisty single and double-track trails! Hiking/trekking poles are permitted at this venue.
Course Markings
Courses are marked with colored surveyor ribbon, placed approximately every 200 meters along the course. Turns are marked heavily on the inside of the turn, with ~3 ribbons placed just before and just after the intersection. There will also be 8.5″ x 11″ laminated signs and flour arrows on the ground (when allowed) at critical or complicated sections. The detailed course map displays which colored ribbons must be followed for each route. Please keep in mind if you are running a longer distance, you will likely need to follow more than one color while out on the course. The most important course marking is the blue ribbon. Blue ribbons indicate “wrong way” trails. You will see blue ribbons, but do not run past a blue ribbon or you will be heading off course!
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, Gu Stroop-Waffles, trail mix, pretzels, potato chips, Oreo cookies, Pop Tarts, PB&J sandwiches, M&M’s, Mike & Ike’s, boiled potatoes with salt, Coke, Mountain Dew, Ginger Ale, water, Skratch Labs Hydration mix , salt tablets, and seasonal fresh fruit. 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.
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).
Drop bag services are not available.
Cupless Event
This a cupless event, meaning aid stations will not have paper cups available for runner use. Each runner will be responsible for carrying their own water bottle or reusable cup. Reusable cups are made of silicone, are collapsible, and easy to carry with you while you run. Going cupless will keep hundreds, or thousands, of paper cups from being thrown away or left littering the trails. Read more about our cupless events here. Reusable cups by HydraPak will be available for purchase at each event for $5.
Run with us at the Reservoir!
VOLUNTEER
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.
To volunteer for this year’s event, please submit our online volunteer form.

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.
Please refer to our online FAQ page for answers to other commonly asked questions.
