As the summer mornings start to cool, join us for a fantastic end-of-season celebration at our 14th annual Runapalooza! From our new venue at Colorado Tap House, you'll have the chance to tackle relatively gentle 5K and 10K courses that go along the acclaimed Ralston Creek Trail, taking you through shady, creekside beaty along Arvada's picturesque open spaces and charming golf course communities. Or our challenging half marathon course that combines the beauty of the Ralston Creek Trail with the challenging Blunn Reservoir loop with its gorgeous Denver and Front Range views. This event, paired with its Endless Series' counterpart Mardi Crawl, offers a can't-miss opportunity to experience the best of what Colorado has to offer!
