Michelob ULTRA Dallas 13.1 Cancelled In light of the anticipated heavy rainfall and flooding expected to impact North and Central Texas, bundled with our concerns for the safety of athletes, volunteers and spectators, we have made the difficult decision to cancel the Michelob ULTRA Dallas 13.1. This decision was made in collaboration with local officials and weather experts, who have stressed that the storm presents potentially dangerous conditions. While refunds are not provided for cancellations due to inclement weather, given this unanticipated cancellation please expect that we will evaluate alternate options and provide more information to you as soon as possible. We regret the inconvenience caused by this change as we work to prioritize participant safety.
