The lay of the land
Connecticut runs a year-round race calendar, so there’s almost always a race near you. The calendar is busiest in October, September, and November, with races most often held in Roxbury, Cornwall, New Haven, and Hamden.
Races in Connecticut wind through the rolling hills of the Litchfield Hills in the northwest and along the Long Island Sound shoreline to the south. Courses tend toward rolling, wooded road and trail routes inland and flatter, breezy coastal routes near the water.
Conditions vary widely by region across Connecticut, so weather lives where it’s accurate — each race page shows its typical race-day high, low, and rain chance from NOAA climate normals for that venue and date.
