BMW Dallas Marathon

The BMW Dallas Marathon begins and ends at Dallas City Hall. The full marathon route circles White Rock Lake before returning downtown. This December road race weekend in Dallas, Texas, centers on the marathon but also includes a half marathon, 5K, 10K, a two-person half-marathon relay, a five-person marathon relay, and a 50K ultramarathon. The marathon is Texas' oldest, originating from the White Rock Marathon first organized by Talmage Morrison of the Cross Country Club of Dallas. Finish times can qualify runners for the Boston Marathon, attracting participants aiming for standards alongside those pursuing more accessible goals in the shorter races and relays. White Rock Lake has been integral to the race since its inception. The initial course circled the lake twice, subsequent versions utilized multiple loops on the east side, and the current marathon course goes around the lake once. The half marathon bypasses the lake loop, while the 50K incorporates an out-and-back segment on Santa Fe. The inaugural race had 82 starters and 61 finishers, a modest number compared to recent race weekends that attract over 30,000 participants across all events. The event also maintains a long-standing charity affiliation with Texas Scottish Rite Hospital for Children, having raised over $3.8 million since it became the primary beneficiary. While BMW now sponsors the event, the historical White Rock identity highlights the lake's significance to the course.
