The 10k race follows a multi-lap course on forest trails. The longer races extend this challenge across similar rolling woodland terrain. This event is suitable for novice trail runners, experienced runners seeking a hilly challenge, and marathon runners desiring a more demanding course than a flat road race. It welcomes pets, and the venue is family-friendly, offering an on-site cafe, Go Ape, adventure play areas, biking trails, and a nearby Gruffalo trail for children.

At Enigma Fireworks, runners circle Caldecotte Lake repeatedly: 7.5 clockwise laps for the marathon or 3.5 for the half. The two-day event is based beside the lake in Milton Keynes, near the hotel and pub car park area, and each day offers both distances in November.
The format is straightforward: everyone runs clockwise on the same lake loop, with water and toilets available every lap. Course details are provided at the venue, runners must attend a briefing ten minutes before the start, and the race team includes a starter, timekeeper, and referee.

Registration opens thirty minutes prior to the start, and a mandatory briefing occurs ten minutes before runners begin.

Moo-rathon, Calf and Hen K
Moo-rathon, Calf and Hen K is a farm-themed running event held at Hyde Hall Farm in Buntingford. It offers 10K, half marathon, marathon, and ultra distances on the same day. The race is structured as a loop, starting and finishing at a base camp on the farm, rather than a point-to-point course. Runners can choose start times with either a six-hour or four-hour cut-off, accommodating both fixed-distance goals and attempts at new distances.
The course is contained within the farm's grounds, featuring a mix of trail, grass, and some tarmac. Exclusive use of the main area helps maintain a compact and easily navigable field. A standard half marathon consists of five laps, with the possibility to extend on race day. The ultra distance typically begins with nine laps and can be increased if time permits. This lap format ensures the aid station is consistently located. Past participants have included individuals running their first 10K, half marathon, marathon, or ultra, as well as seasoned regulars. All finishers receive a custom medal, and on-site parking is provided.

Solo participants must be over 18, start at 8:00 am, and have 13.5 hours to complete the race, with progressive cut-offs at checkpoints.
The circular course connects cross-country trails, villages, towns, two country parks, Salcey Forest, the Grand Union Canal, and segments of the Nene Way, Midshires Way, and Northampton Round. The route is marked but requires some navigation, allowing runners to use a tracker and voice-cue app. Six checkpoints are positioned 6 to 8 miles apart and provide water, snacks, and Go Beyond Fruit Cake. A relay option divides the same route into seven legs, with team formats for three, four, or seven runners, plus a driver if necessary.
