The Dallas Vert Mile is an awesome stair climb race and fun walk at Reunion Tower on March 25, 2017. There are three vertical - or vert - distances available. All participants do the Vert Sprint Race and Fun Walk, which climbs 50 floors and nearly 500 feet. In addition, you may also do the 3-lap Vert 1/4 Mile, or the 12-lap Vert Mile Challenge. The challenge is to finish all 12 laps before the two hour time limit. The event will benefit participants - who will get stronger, fitter, and happier - along with a number of non-profit organizations.
