In reply to Removed Useralastairmac1:
I'm not UK based or registered for that race but am running UTMB which has just been confirmed to go ahead. They've stated that they'll be allowing European runners signed up to the 'Passe Sanitaire' scheme that the French government are putting in place (basically proof of double vaccination, negative PCR test or proof of past Covid recovery).
There will be a staggered start over 3 hours to ensure a bit more distancing and we'll have to wear masks at aid stations I guess.
The French government are announcing more details on 9th June as the final phase of déconfinement. Not sure what the situation is in Spain or how it would work (for Val d'Arran would you fly to Pau/Toulouse or somewhere similar?) with the situation there (isn't it mostly in Spain?).
Best of luck anyhow.
