Grandma’s Marathon Event Alert System


Ever wonder what the colored flags you see along the Grandma’s Marathon and Garry Bjorklund Half Marathon course mean? Before the big race, take some time to familiarize yourself with the flags and what they mean on race day.

Grandma’s Marathon uses the Event Alert System (EAS) to communicate information on current course conditions pre-event and on race day. EAS is a color coded classification that communicates the risk level of course conditions.The levels range from low (green) to moderate (yellow) to high (red) to extreme (black) based on a variety of factors. (See chart above for further explanation).

Participants, spectators and volunteers should familiarize themselves with the color-coded flags which will be posted pre-race at the Essentia Health Fitness Expo. Flags will be at the starting lines and at each water station on race day. Updates may also be communicated over public address and by race officials.

Note: 2017 is the first year Grandma’s Marathon is using the Event Alert System (EAS). 

Further Safety Information:
Automated External Defibrillators (AEDs) and trained responders are located at each mile along the race course.

Medical assistance is available at the medical tent in the Finish Line Area until 2:45 p.m. – use hospital/emergency room services after 2:45 p.m.

Please complete the emergency medical information on the back of your race bib.
