230 in 24 hours offroad at the CLIC 24 a few years back. Loved every second, one of my best rides ever. Misty sunrise over the Mendips, views to the sea and Wales, bluebells, dusty rocky singletrack, didn't want to finish. Felt fine while still on the bike, could easily have done 240 or 250 in the race if not for faffing with fitting borrowed lights and having no support for 1/2 the event, and could have carried on for a while longer after the 24 (I finished with just less than my fastest lap left before the end, and your last lap doesn't count if you're in after 12 noon). Getting off the bike and packing kit away wasn't too pleasant though!
