When you see signs for the Garmin Segment Challenge, run your hardest for the next quarter-mile! (This will be at mile 4 for the First Half and mile 11 for the Full Marathon.) Timing maps will be at the bottom and top of Conzelman Rd.
Each male, female and non-binary runner with the fastest segment time will take home a Garmin Forerunner® 255 device.
