The 5K is a loop on quiet roads with right-hand turns and one water table. Weston roads are not closed to traffic during the races. Kids runs take place on the high school track with distances set by age and field size. Half marathon finishers receive finisher medals. Overall male and female top three in both the half and 5K receive gift card awards of $100, $75, and $50; standard age-group awards are also specified. No dogs are permitted in either race.
