Hell on the Humber, or 'HOTH' as it's affectionately known to the thousands of runners who have taken part over the years, is a series of endurance races that take place each year on the world famous Humber Bridge.
The events, which extend in endurance from 6, 9, 12, and 24 hours, involve participants running, walking, or crawling four mile laps across the bridge and back, from East Yorkshire to North Lincolnshire over the mighty River Humber.
There are four events in the series, each with their own unique challenges:
The Mad Hatter
6 & 9 Hour daylight races starting at 9am and 1 2 respectively on the last Saturday of March, and finishing at 6pm.
A challenging night race of 6 & 12 Hours, which tests the psychological and physical endurance of participants as they run through the darkness towards dawn (or midnight, in the case of the 6 hour.)
Helloween is a fun, fancy dress version of HOTH that runs for 6 Hours between 6pm and midnight on the last Saturday of October, the day closest to Halloween.
6 hours of festive running on the first Saturday of December, it starts at midday, and finishes at 6pm, an hour after being plunged into darkness. This is event is known as the longest Santa race in the world!
