Boring Half Marathon
Race Day Weather
Comfortable temps, rain likely
Mild 55°F temps at gun time mean comfortable early miles without overheating risk. Light winds shouldn't be a major factor for pacing. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. Moderate humidity at 78% is worth noting for effort level, especially in later miles.

Race Info
The Half-Boring Half Marathon is a paved out-and-back on the Springwater Trail. It starts at Boring Station Trailhead Park in downtown Boring, runs toward Gresham to a turnaround at Towle Road, and returns to the same park for the finish. The trail parallels county roads with a single signaled road crossing, and the course is mostly wooded, with views of Mt. Hood on clear days.
