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.

The entire course is paved. The full marathon course is two out-and-backs of the half-marathon course. 

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

*The certification is under the old race name, but applies to the new name as the course is unchanged.

Water and electrolyte drink will be supplied at all aid stations. Additional assistance will be available to runners in the form of sweep vehicles.
