Prepare for an unforgettable trail experience at the Badger Cove Half Marathon, 10K, and 5K, set to challenge and inspire runners on April 18, 2026, in Livermore, CA. This highly-regarded event, part of the Brazen Racing Ultra Half Series, invites you to conquer the stunning emerald hills of Lake Del Valle Regional Park. While the 5K offers a mostly flat route, the 10K and Half Marathon distances are renowned for their challenging, hilly terrain, featuring significant ascents and descents that make them a true test of grit and endurance. Expect 95% unpaved trails, offering breathtaking waterfront views under oak groves and panoramic vistas, though trails can be muddy if there's been recent rain.

The Half Marathon boasts approximately 2,000 feet of elevation gain, reaching a maximum elevation of 1,100 feet, making it a course where personal records take a back seat to the sheer accomplishment of finishing. Runners praise the fantastic aid station support, which are well-stocked with water, sports drink, gels, pretzels, candy, and cut-up fruit, with multiple stops along the half marathon route. Embracing sustainability, the race encourages half marathon participants to be "cupless," refilling their own hydration vessels at aid stations. Typical race day conditions in April offer pleasant weather, with highs around 72°F and lows around 46°F, and only a 4% chance of precipitation, providing ideal conditions for a demanding trail run.

Beyond the challenge, the Badger Cove Half Marathon is celebrated for its vibrant atmosphere and strong community spirit. Finishers are rewarded with custom medals and shirts, along with a delectable spread of post-race refreshments, including local favorite It's It ice cream, salty snacks, fruits, pastries, and bagels. Whether you're an experienced trail runner seeking a demanding course or a hiker looking to immerse yourself in nature, this event welcomes all abilities, even offering an early start for half marathon hikers. Join the Brazen community and discover why this race, with its unique "Leprebadger" charm, is a beloved fixture on the California trail running calendar.
