Jack o Lantern Revenge 5K

Jack o Lantern Revenge 5K is held in Wilmington, Delaware, on November 8, 2026, with a single 5K starting at 10:00 a.m. The mid-morning start makes it a relaxed morning by racing standards: there is time to eat, travel and warm up properly rather than rolling out of bed straight into a start corral.

Held the week after Halloween, this one falls at a point in the calendar where many runners are between goals, which is exactly when a 5K earns its place. Race it hard and you get an honest measure of your current fitness in under half an hour, with almost no recovery cost afterward. Four to six weeks of running three or four times a week will get a first-timer to the finish; if you are already fit, add one session of 400 to 800 meter repeats a week and go for a time.
