Do I have to stay up for 24 hours?

It is a 24 hour event, we do not timetable for sleep and activities run for 24 hours. However we do recommend you bring a tent for when it all gets too much and you need to get a little rest.  However we would encourage you to camp light the less you bring, the less you will need to packup at the end of a long and tiring 24 hours.
