A programme of events around the theme Endurance starts on the 24th of April and runs until the 26th at Vivid.
Endurance is a three-day programme of screenings, performances and exhibition exploring the physical and mental limits of human endurance
There really are a lot of events to investigate, even if you can find the performative and body-art aspect of this sort of work a bit challenging (which, if you ask me, is even more of a reason to go), there should still be something of interest. a timetable for the events can be downloaded here.
I think I will at least try and make it to the William Hunt (pictured) piece on the Thursday night.
