Staring Times

The Full Marathon will start at 8:30 AM.

The Half Marathon will start at 8:40 AM.



The certified (VT15301JK) marathon and half-marathon begin and end near the house where Clarence H. DeMar, seven-time Boston Marathon Winner, once lived. The half-marathon course is out and back on the west shore of South Hero and Grand Isle; a land of farms, apple orchards, and summer cottages. The terrain is flat to rolling.

NEW IN 2021: The entire course is newly paved. The full marathon course is two laps of the half-marathon course. This helps us improve our logistics and provide a better experience for our racers. 

The time cut off for the marathon is 6 hours.  The time cut off for the half-marathon is 4 hours.


Aid Stations

There will be an aid station approximately every 2 miles starting at mile 2 and stopping at mile 24 for a total of 12 aid stations (2-3 porta-potties on course). Water and electrolyte drink will be supplied at all aid stations. Additional assistance will be available to runners in the form of sweep vehicles.
