Des Plaines River Trail Marathon
Race Day Weather
Cool morning, gradual warming
Runners will face a starting temperature of 55°F, peaking at 66°F. A light wind from the S will offer some resistance, with gusts up to 24 mph. With humidity around 63%, it's advisable to hydrate regularly and adjust pacing as temperatures rise.
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).
