About the Reservoir Run Half Marathon
The Kiwanis Club of Weston has put on the Reservoir Run for well over a decade, and it has settled into a late-October fixture for Fairfield County runners. Proceeds go to children's and community organizations, and the small-town feel is genuine rather than manufactured.
Course
The loop leaves Weston High School and reaches the Saugatuck Reservoir at its northern end in the first half. A long downhill past the dam drops onto flat road along the Saugatuck River near Devil's Den, and the payback comes late: a sustained climb through mile 12 back up to the school. Save something for it.
Race-day weather
Late October in Weston often starts in the 30s or 40s and stays cool through the morning. Frost is possible early, wind is usually modest on the sheltered roads, and foliage is near peak.
