We leave next Tuesday. Still last minute changes to our return flights, hopefully resolved with no more changes. There is a lot of little details regarding covid documents etc. but gradually getting things sorted out. I think the race will be the easiest part of it all. We scheduled rapid tests in the Zurich airport the night before we fly back here etc.Good Luck, although my guess is that if you went you are already there getting acclimated with the UTMB slate of races getting started next week.
But it's worse for unvaccinated travelers, I wouldn't even do it if I wasn't.
