Comfortable temps, warming through the race

Starting at 62°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temperatures rising to 72°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 75% is worth noting for effort level, especially in later miles.

Race Info

The Half Marathon is a single loop of about 13 miles on the trails of Kennedy State Forest between Virgil and Harford, New York. The course links the Spanish, Swedish and Ukrainian loop trails with a section of the Finger Lakes Trail in the western part of the forest, between Daisy Hollow and Babcock Hollow. It is mostly rolling single track through hemlock groves and hardwood forest, with about 2,200 feet of climbing and a hard hill in the last two miles. Age- and gender-based head starts let older and non-male runners start earlier, so finishing order follows the clock.
