Under Armour's second annual Mountain Running Series kicked off at Colorado's Copper Mountain on Saturday, July 14.
Boston has one of the best running cultures on the planet. A walk through downtown on the eve of the marathon is all the evidence you need. Every shop, street corner and sidewalk is emblazoned with good luck messages and supportive cheer. The city estimates that more than 1 million spectators will be out on the course tomorrow! Good luck to all the runners and we hope you soak in all these positive vibes.
