I’m camping at the elephant campsite and intend to head back to the UK Sunday night. The last Eurotunnel crossing is at 22.42, has anyone got any experience/advice as too realistic it is to be able to make it back in time to catch this crossing? Allowing an hour for check in and 3hours 20 mins travel time as given by route finders, which are obviously not realistic on race day I would need to leave Spa by 18.20. Any comments appreciated folks. Thanks.
