Delaware runs a year-round race calendar, so there’s almost always a race near you. The calendar is busiest in November, October, and December, with races most often held in Wilmington, Newark, Lewes, and Rehoboth Beach.
Races in Delaware sit almost entirely on the flat Atlantic coastal plain, with low-lying farmland inland and beach towns like Rehoboth and Lewes along the shore. The terrain stays flat statewide, making for fast, straightforward road courses and easy beachfront runs.
Conditions vary widely by region across Delaware, 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.
