Tony Sedman pointed out that there’s some doubt as to whether MRD lasts 35 or 36 hours. I’m not sure myself! I’ve seen both times from different members of the organising team. I would think if you’re still on the key at 2300 (which will be midnight by then, BST) you won’t care if it shuts down then or at 1 am – you’ll probably be in bed anyway!
