Forbidden Forest 30 Hour Ultra Run

Forbidden Forest 30 Hour Ultra Run is a fixed-time trail event in Stratford, Connecticut, that starts at 8:30 AM on October 3, 2026. The single format is a 30-hour race: the clock runs through Saturday, overnight and into Sunday afternoon, and your result is the total distance you cover before it stops.

Thirty hours is an unusual and generous window. It gives runners chasing 100 miles a little more room than a standard 24-hour race, and it gives first-time overnight runners a chance to see how their body handles a full night on the move without any distance obligation. Because you can rest, eat and change gear whenever you like, the race is as much about strategy as fitness: decide in advance how you will handle the dark hours, when you will take breaks and what you will eat. Train with time on feet in mind, including at least one long night run and back-to-back long-run weekends over a 16-to-20-week build. Coastal Connecticut in early October can be mild by day and cold at night, so pack layers for both.
