3 Days at the Fair Course Guide

Every race at 3 Days at the Fair runs the same certified 1.000-mile flat loop at Sussex County Fairgrounds, lit at night so no headlamp is required. The timed races form a ladder from 144 Hours (6 days) down to 6 Hours, each starting on its own staggered day so every race's clock stops together at 9:00 AM Sunday: 144H starts Monday, 72H starts Thursday, 48H starts Friday, and 24H/12H/6H start Saturday, with earlier optional start days available for the shorter races. On top of the timed ladder, there is also a certified Marathon (a Boston Qualifier course) and a certified 50K, either of which can start any morning at 9:00 AM during the week.

The loop itself is flat, mostly paved, and about as forgiving as ultra terrain gets, roughly 95% pavement and 5% crushed gravel. The difficulty is entirely about duration and repetition: the 144 Hour option asks you to keep moving, with sleep, across the better part of a week, on the same 1-mile loop. Even the shorter 6-hour and 12-hour races test focus and pacing on a course with essentially no scenery change. It rewards patience and fueling discipline over raw speed.

This is one of the best-supported ultras you will find on fueling logistics: one aid station runs continuously from 9:00 AM Monday through Sunday morning, staffed by an ultra-running crew, stocked with hot and cold food and dedicated vegan and vegetarian options throughout the event, plus access to a walk-in refrigerator and a full kitchen if you want to cook your own food. Aim for roughly 60 to 90 grams of carbohydrate per hour while moving, and use the loop's constant aid access to eat real meals rather than relying only on gels, especially on the longer timed races.

The official race clock stops at 9:00 AM Sunday for every single race, regardless of which timed distance or start day you chose. Since only completed laps count toward your total mileage, there is effectively no mid-race cutoff to worry about, just the shared Sunday morning finish for the whole event. Marathon and 50K entrants must finish before the next scheduled race start after their own.

Beyond top-3 male and female local artwork awards for the greatest mileage in each timed category, the race runs a genuinely unusual lifetime-mileage coin program (100, 250, 500, and 1,000 lifetime miles, with stained-glass awards for 2,000-plus) and single-event belt buckles for reaching 101, 202, 303, 404, or 505 miles in one event. There are also Marathon and 50K finisher coins, and a Quadzilla coin for running 4 marathons or 50Ks in the week, or a Hexazilla coin (with a special six-sided coin) for completing 6 separate events.

The certified Marathon (a genuine Boston Qualifier course) or the 6 Hour timed race are both low-commitment ways to try the format without signing up for multiple days. The flat, lit, fully supported loop removes almost every logistics headache of a normal ultra: no navigation, aid available around the clock, heated showers, and a kitchen if you want a hot meal mid-race. The mental side, running the same 1-mile loop for hours or days, is the real test, and it is a different skill than covering technical trail. Day-of registration is available, but the event does close online registration the Wednesday before it begins, so plan ahead if you want the better entry pricing.
