Enjoy fireworks at 12:01am on the 4th, a parade, street vendors, kids’ activities and more! The biggest bang comes later that morning with the town's famed race, Mount Marathon. The course is straightforward, but far from easy: start downtown, run to the top of the 3,022-foot mountain, then run back to the finish. It is rumored the race originated as a bet between locals that the mountain could not be tackled in less than an hour. Seward.com
