As the summer mornings start to cool, join us for a fantastic end-of-season celebration at our 12th annual Runapalooza! From the award-winning Apex Center, you'll have the chance to tackle relatively gentle 5K, 10K, and half marathon 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. 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!
