The Bontrager TwentyFour12 takes place at Newnham Park in Devon over the weekend of the 7/8th July. You can ride for 12 or 24 hours solo or in teams and for those who work best late at night there's the 12 hour torchbearer solo which starts at midnight. This event is reported to have a brilliant course, so it should be great fun whether racing seriously or out for a laugh.
