Yellow Belly 100 Mile Ultramarathon
Yellow Belly 100 is a 100 mile ultramarathon held on 27 March 2027 that follows one continuous loop of the Lincolnshire Wolds Area of Outstanding Natural Beauty. The course covers approximately 8,000 ft (about 2,438 m) of cumulative ascent and descent and includes sections of the Viking Way and a series of historic Lincolnshire villages.
The event uses Swallow Village Hall, Lincolnshire LN7 6DL, as the base location. The field is strictly limited to 150 runners and entries operate on a first come, first served basis. Support on course includes six fully stocked aid stations and GPX files are available for route navigation on OS Maps and Garmin devices. A mandatory kit list and race day information are provided to entrants.
A 36 hour cut-off applies to the course. Finishers who complete the route within the time limit receive a bespoke Yellow Belly finisher’s medal and a Yellow Belly Pale Ale. Prizes are awarded to the first three finishers in the male and female categories. Parking at Swallow Village is limited; additional parking is available about 200 m from the start near the Swallow Inn.
Entry fee for the event is £150. Visit the organization's website for the most recent information.
