Dallas

Dallas has been a marathon town since 1971, when the first Dallas White Rock Marathon drew 82 runners around White Rock Lake — making the race, now the BMW Dallas Marathon, Texas' oldest continuously run marathon and Dallas' largest single-day sporting event. Beyond the marathon, Dallas's calendar leans into its sprawl: IRONMAN 70.3 Dallas–Little Elm covers the lake-country suburbs, while trail-leaning events like the Rockledge Rumble and Isle du Bois push into the greenbelts and lakeshores north of the city.
