The Experience
Now in its 14th year, Runapalooza in Arvada, Colorado, offers a challenging half marathon that threads through the shady Ralston Creek Trail before tackling the tough Blunn Reservoir loop. Runners are rewarded with sweeping views of the Denver skyline and the Front Range. With a median field of about 96 finishers, the race retains an intimate, local feel—repeat runners make up roughly 5% of the field. The course also features 5K and 10K options on gentler creekside paths. Starting and finishing at Colorado Tap House, the event pairs with the Endless Series' Mardi Crawl for a celebratory end-of-season atmosphere. It's a hidden gem for those seeking a low-key but scenic challenge.
