To produce an awesome race, we coordinate our efforts and plan well in advance, making it difficult and costly to make changes after registration. Medals, bibs, shirts and other items are ordered months before the race and purchased according to the original information provided during registration. As a result, and similar to other races in the industry, iRun Texas and Split Second Productions does not offer refunds of registration fees for any reason. In addition, release forms and emergency content are specific to the individual participant. Transferring such information would be a liability to the participant as well as the race. This policy applies to individuals with injuries, unexpected business, family emergencies, etc. There are no exceptions.
