(230)

Inside Trail Racing (ITR) was founded to provide a competitive yet amateur-approachable race environment that challenges all abilities and presents the beauty of the varied West Coast trails. With distances from 5K to 100K, we are committed to serving every participant an ambitious, fun, and well-supported trail-running event. Our long-distance events rank amongst the most popular events in the country, attracting world champion mountain- and ultra-runners and delivering courses even more strenuous than The North Face Endurance Series. It is our mission to work within the trail-running community as a cooperative, encouraging entity upon whom both runners and hikers can depend.

Berkeley Trail Adventure this past weekend was an absolute delight!

The miles, the smiles and oh yes, TRAILS!

If you want a challenge but you still want to have a good time and feel supported, Berkeley Trail Adventure is just what you are looking for.

6,800'+ of elevation gain in the 50K, to far? 4,600' + of elevation gain in the 35k, want elevation but not the distance? How about 2,800' + in the Half Marathon?

You want it, this course has it.

Inside Trail Racings 2026 edition of the Napa Lapa Trail Adventure...

08/12/2026

Our 2026 edition of the second annual Napa Lapa Trail Adventure.

An endurance event to test the boundaries. We give participants 3, 6 or 12 hours to complete a 4.16 mile loop as many times as possible, then for the final 40 minutes of the duration we open a 0.34 mile loop for emptying out the tank.

Each big loop has 815' of elevation gain (pain). Over a 50k of running (8 big laps) runners get in 6,500'+ of vertical gain (or 7 big laps + 7 small laps)

Small loops are 3x = 1 mile to make easy math

The second Annual Napa Lapa Trail Adventure presented by Omen W**e - Atlas W**e Co at Skyline Park Napa was a success!

Runners got in mileage and vert completing loops of 4.16 miles. The day started cool and overcast that quickly burned off by the time the 3 Hour runners were wrapping up their day. Then, the sun and heat came out to treat the 6 Hour and 12 Hour runners.

Don't let the 815' of posted vert fool you, for a 50k that is over 6,500' of vert pain/elevation gain! This Napa Lapa Adventure is no joke!

We had the iTR Rejuvenation Station for runners to cool off in w/ misters & ice buckets. Skratch Labs: Fuel + Hydration & Pickle Juice keeping the rPickle Juiceted holding off the muscle cramps. Spring Energy & JAMBAR CerSpring Energyc EJAMBAR Certified Organic Energy Bard.

Congratulations to all who participated and became a Napa Lapper and to all the crews helping get your friend, partner, sibling, son and daughter through the day.

We had a great day, we hope you all did too! Thank you for trusting us for your trail adventures.
