Cool start — fast day potential, big temp swing

A cool 46°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temps will climb significantly to 65°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. Moderate humidity at 69% is worth noting for effort level, especially in later miles.

The DPR Trail is truly awesome and the color changes are OMG-worthy! You'll run through beautiful alternating lush forests and open wetlands on a very flat, wide, crushed gravel trail, free of roots and rocks. All of the major road crossings are managed by way of bridges or viaducts (with only 4 minor road crossings along the whole 50K/50 Mile course, 2 on the Marathon course, and none for the Half Marathon course).
