The inaugural Pena Passage, Lagoon Valley's Trail Race, presented by Altra, promises runners and hikers of every stride and skill level a scenic and adventurous trail race. Set against the stunning backdrop of Lagoon Valley Park’s rolling hills, shimmering lagoon, winding single-track trails, and fire roads, this event offers three distinct distances to challenge and delight participants.
The 5K course weaves through gentle terrain, ideal for first-time trail runners with some adventurous single track included, families, and those looking for a fun yet invigorating run or hike.
In contrast, the 10K route introduces slightly more rugged sections and elevation, testing endurance while rewarding runners with sweeping views of open grasslands and shaded oak groves.
For seasoned trail enthusiasts seeking a true test of resilience, the 30K distance presents every challenge of the 10k route but times three! Runners will traverse a mix of technical trails, climbs, and descents that showcase the park’s natural beauty and varied ecosystems.
Each course is thoughtfully marked and supported, with aid stations positioned to keep athletes hydrated and motivated. The following is a list of some of the foods and beverages each aid station may provide: Electrolyte drink, Energy gels, chews, pretzels, Oreo cookies, water, M&M’s, bananas, and watermelon! Whether competing for personal bests or simply soaking in the camaraderie of the trail running community, participants will find the Pena Passage, Lagoon Valley's Trail Race an unforgettable experience that celebrates both the spirit of competition and the tranquility of nature.
The Kids Fun Run at the Pena Passage a Lagoon Valley trail race is all about smiles, movement, and big finish-line energy. Young runners dash up the scenic trail with cheers from parents and volunteers echoing through the route. It’s a short, playful race that celebrates effort over speed and confidence over competition. Every kid leaves feeling like a champion—and usually asking when they can do it again.
