RACE INFO
The Napa Lapa Trail Adventure is Inside Trail’s first time-based run. This means that instead of running a pre-determined distance as fast as possible, you’ll be running as far as possible during a pre-determined amount of time. And what other place could be better than the beautiful, rolling hills of Napa’s Skyline Wilderness Park?
Skyline Wilderness Park is located in Napa, California. In 1979, the land beside the State Hospital was declared to be surplus and was to be sold to a private party. A group of concerned citizens got together and enlisted the help of various members of the community and government to allow the group to use the land as a park for the Napa Valley. The idea of a park was formed, a constitution was created, incorporation papers drafted, environmental impact studies made, etc. Since there has never been a private sector leasing state land for a park system, the State leased the land to the County of Napa which then subleased it to the Skyline Park Citizens Association. More on the history of Skyline Wilderness Park here.
Skyline park has 25 miles of multi-use fire road and singletrack trails of various skill levels. As a memorial to Martha Walker, the Martha Walker Native Habitat Garden in Skyline Park was created, inviting visitors to enjoy a unique presentation of flora from all over the State.

The Napa Lapa Trail Adventure will go from 7:00 AM – 7:00 PM! What’s fun about this event is that you can run a lap, take a break and head out again when you are ready, as long as your race is still open. Whether you get in 1 lap or 20 laps, you have finished the race, you are now a Napa Lapper!
Each main loop (big loop) will be 4.16 miles long. Test yourself and see how fast and how many you can complete. Each loop has approximately 815′ of elevation. For reference, 1 lap per hour is 14:25 min per mile; 2 laps per hour is 7:13 min per mile
The last 40 minutes of each timed event we will open our “small loop” for you to close out your running time. The loop will be 0.34 miles long.
Test your mental game, decide to go out for another big loop or sit around and wait for the small loop to open!
This is Inside Trail Racing style, lots of elevation gain!
Plenty of Awards to go around:

DETAILED COURSE INFO
Printable Course Information
Course Composition
The vast majority of the Napa trail run will be run on fire trail and moderately technical dirt trails. The course has single track, long smooth hills and swooping descents the entire way, as well as 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 Napa trail run 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
At the Napa trail run, there will be one full aid station at the Start/Finish. There will be a water station at mile 2 (water only). Everyone needs to head up to the Water Station for the turn around to complete the full course.
Skratch Hydration Mix: Most sports drinks are too sweet, too fake, or too hard on your gut. Skratch is made with real fruit for light flavor, the right balance of sodium and sugar for faster absorption, and none of the artificial stuff that causes GI distress. It’s designed to replace exactly what you lose in sweat — and nothing you don’t.
Pickle Juice: Pickle Juice® uses a proprietary blend of all natural, organic ingredients that immediately interact at the back of the throat to block nerve signals being sent to muscles.
Spring Energy: Remove barriers between you and your best effort by creating innovative and healthy products for runner, triathletes, cyclists and all other athletes. Products that work with your body not against it!
Move better. Feel better. Finish stronger.
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: Spring Energy, Pickle Juice®, trail mix, pretzels, potato chips, Oreo cookies, PB&J , M&M’s, boiled potatoes with salt, Coke, 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 stations 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 for the 6 hour will be located by the Start/Finish area.
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 and soft flasks 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. We will be selling reusable cups ($5) and 500ml Soft Flasks ($15) at the event.
Test your Endurance at The Napa Lapa!
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.

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.
