What do the colored flags mean?

Colored flags will be located at each mile marker along the course to serve as a communication device to runners advising of weather- or course-related problems. Please pay close attention to these flags on race day! Here is what each color designates: 

GREEN FLAG: GO - Proceed as normal. 

YELLOW FLAG: CAUTION - Slow down, use caution and drink plenty of water due to heat.  

RED FLAG: EXTREME CAUTION - Slow down, use extreme caution and drink plenty of water due to dangerous weather conditions. Timing of the event has stopped and no awards will be issued. But one big post race party will continue!

BLACK FLAG/CANCELLED: Stop! Race has been cancelled due to extreme weather or course emergency. All participants should turn around and head to the finish line or seek shelter. Staff and volunteers will be there to support and direct you.
