Saturday, May 17th and Sunday, May 18th: Need another reason to tour the city? The Colfax Marathon has what you’re looking for. Huff, puff, cry, crawl, and celebrate as you roll through 26.2 miles of Denver’s urban terrain. The good news? There're also a half marathon, 10 miler, and a 5k if you're not up for the big one. The even better news? No matter which one you run, you'll get to enjoy free beer, plus BBQ from Jim ’N Nick’s Bar-B-Q, at the after party. Lace 'em up!
