Registration for The Colony Shoreline Trail 15K and Green Dragon 5K, previously known as The Colony Half Marathon and Green Dragon Five Miler, is now open. Join us this year to run through the beautiful Shoreline Trail and Ridgepointe neighborhood in The Colony, Texas, at 8:00 a.m. on Saturday, October 21, 2023. It’s a flat course, great scenery, even better weather, free post-run beer and did we mention that quarter zips are back? Proceeds benefit Angels Fall Up to support cancer research. About 85 percent of this race will take place on The Colony's Shoreline Trail, a 3.5-mile out and back crushed granite trail that overlooks the beautiful Lake Lewisville.
