Weekend Heat Advisory

Jon Hughes, Race Director, and Dr. James Scelfo, Medical Director, would like to welcome you to The Twilight Zone Tower of Terror ™ 10-Miler Weekend. As the runDisney team makes final preparations for Saturday night's main event, the 10-Miler, we want to remind you of important weather related preparations and information.

Due to warmer weather than anticipated, we encourage all participants to closely monitor their pace and not overextend. This may not be the event to attempt your personal best. We encourage you to be well-hydrated prior to the race and maintain fluid status with alternating water and electrolyte based hydration options throughout your race and entire race weekend. Slow down and ask for assistance at any and early signs of heat illness. Heed these warnings seriously.

Please review the race program for more details, but as a reminder all medical stations will have the appropriate flag color displayed according to existing heat conditions:

  • GREEN FLAG – Good conditions. Enjoy the event but stay alert.
  • YELLOW FLAG – Less than ideal conditions. Participants with high risk of heat stroke should withdraw.
  • RED FLAG – Potentially dangerous conditions. Heat injury is possible. All participants urged to slow their pace and hydrate adequately.
  • BLACK FLAG – Extreme and dangerous conditions. All participants advised not to compete. Course may be shortened and no times recorded.
