The Pretzel Run Colorado invites you to immerse yourself in a festive Bavarian atmosphere while conquering your chosen distance on October 10, 2026, in Louisville, CO. Offering a Half Marathon (13.1M), 10K, and 5K, this popular event blends the thrill of trail running with an unforgettable Oktoberfest-themed celebration. Expect typical race day conditions to be crisp and cool, with highs around 68F and lows near 39F, and only a 7% chance of precipitation.

Runners will navigate fun and challenging trail courses within Louisville Community Park, the central hub for the race activities. The 5K runners will tackle a scenic "East bound loop" featuring a notable hill between mile 0.8 and 1.1, offering a more demanding route. Meanwhile, 10K participants will experience a flat "West bound" 5K loop before joining the hilly "East bound" section, providing a varied and engaging challenge. The newly added Half Marathon for 2026 promises even more scenic trail exploration. Aid stations along the course provide water, electrolytes, and basic first aid, though runners should come prepared with their own hydration systems as it is a cup-free event.

What truly sets the Pretzel Run Colorado apart is its vibrant post-race Oktoberfest party. All finishers are rewarded with a unique, collectible beer mug-shaped wooden medallion and a traditional 500ml glass beer mug, which grants you a free beer or wine at the lively on-site Bier Garten in Louisville Community Park. Indulge in warm, freshly baked Bavarian pretzels served with an array of imported German mustards, enjoy German Gummi Bears, and soak in the festive ambiance with live polka and Bavarian music. With an event frequently selling out, secure your spot early for this exceptional blend of running and celebration.
