Red, White & Boom! to Proceed as Scheduled

Event to Proceed as Scheduled

Today’s Red, White & Boom! TC Half Marathon, Relay & 5K, presented by Summit Brewing Company, expects to proceed as scheduled. The half marathon race will start at 6:30 a.m. and the 5K will start at 6:50 a.m. unless there is an unexpected change in conditions

With race-time temperatures forecast for 72 degrees with 87% relative humidity and cloudy skies, we continue to anticipate the start-time Event Alert System (EAS) flag color of YELLOW (Caution: Less Than Idea Conditions) for the event. In such conditions, runners are urged to slow their pace and be prepared for worsening conditions.

In light of the conditions, we will allow half marathon and relay registrants to opt into the 5K, if they want to reduce their exposure to the conditions. Runners do not need to inform race officials if they change distances, but must start at the proper start line and start time for the distance they intend to run. Relay team members both need to opt into the 5K, running as individuals.

  • Half Marathon & Relay – Starts at 6:30 a.m. on West River Parkway, across the Stone Arch Bridge from the finish line and festival area (map)
  • 5K – Starts 6:50 a.m. on SE Main Street just north of the finish line and festival area (map)

EAS flags will be positioned at the start lines and along the course at fluid stations. Please familiarize yourself with the EAS flag colors, prepare properly for varying weather conditions and remain alert for instruction from event officials in the case of changing conditions. Also, please familiarize yourself with the Red, White & Boom! TC Half Marathon, Relay & 5K course map, including the location of fluid stations.

Please familiarize yourself with our medical team's advice for running in hot and humid weather, including:

  • Drink enough fluid to keep your urine light yellow in color
  • Dress in light-weight fabrics that wick away sweat
  • Lower your race pace expectations, make finishing strong your goal
  • Use fluid stations to stop to drink and pour water on yourself
  • Monitor your physical well-being, be prepared to slow down or stop

The presence of lightning storms during event set up or while it is underway could prompt delays in the start of the event or even cancellation, if the safety of staff, volunteers or participants is at risk. Twin Cities In Motion will continue to monitor conditions with the support of the National Weather Service and will communicate further updates via email, at, on the Twin Cities In Motion app (download here), and on Facebook ( and Twitter (@tcmarathon).

Twin Cities In Motion’s primary concern is for the safety of participants, volunteers, spectators and the community at large. We’re looking forward to organizing a great race day experience for all our participants. We appreciate your understanding and thank you for running with us.
