2020 Half Marathon Map (New adjusted course for 2020)
The Flag System
We will monitor the temperature, amount of sunlight and the humidity by using the wet bulb guidelines.
Green Flag = low risk. Red Flag = high risk. Black flag = extreme risk. The risk flags will be displayed at the start line, all mile marks and at the finish line.
If the Green Flag is displayed: Go, Go, Go
If the Red Flag is displayed: you should be aware that heat illness is possible. Slow down and take your time.
If the Black Flag is displayed, runners should slow to a walk and walkers should walk very slowly. Stop, rest, seek shade.
NOTE: If the Black Flag comes out, all split timers and mile markers will be removed. Timing and scoring will be closed. Medical people, volunteers, water stops, IMPD officers, pick-up vehicles, etc will remain on the course.
