What is your choice for tyres for the epic? A lot of different terrain means there is probably no right answer but is there a Goldilocks?

This looks epic! I would be a newbie to this, and was going to be flying back to the UK late June to see family which looks increasingly unlikely. And the race looks like an incredible back up plan. I am sure this is on the back of everyone's mind, but equally late June is still a long way off. Has there been any consideration of Covid into planning and chances of this going ahead? before I start upgrading a few key bits of kit!
