Get ready for a day full of scenic running races, including 5K, 10K, half-marathon, and marathon courses. The half-marathon and marathon routes skirt the edge of Rocky Mountain National Park and are certified by USA Track & Field, so finishers with qualifying times can enter their bids for touted races like the Boston Marathon. Bonus: Stop by the nearby Bond Park the day before the runs for interactive programs with park rangers and the Rocky Mountain conservation teams. Sun, times vary.
