Race Info
The Dallas Marathon has started and finished in Downtown Dallas since 1971, when local runner Tal Morrison founded the race with a $25 ad in Runner's World. It was known as the Dallas White Rock Marathon until 2012 and added BMW as title sponsor in 2016. The course leaves Dallas City Hall Plaza, crosses the Margaret Hunt Hill Bridge into the Design District, passes Highland Park, circles White Rock Lake, and returns through Lakewood and the Swiss Avenue Historic District to the downtown finish. It is a Boston Marathon qualifier and has run every December since 1976, missing only 2013 and 2020; race weekend also includes a half marathon, 10K, 5K and 50K ultramarathon. Wikipedia
