Not seen this mentioned but apparently the 70.3 champs is returning to Europe in 2022, either Lahti in Finland or Klagenfurt, Austria.
I reckon Austria would be popular, Finland is nice but may not be that easy to get to, also not sure how much accommodation is in Lahti, but I think it’s a big ski venue?
Edit: Lahti is a lot closer to Helsinki than I thought, only about 20 miles or so.
in some ways, Lahti will be easier to get to for those flying in as it’s only “just” outside Helsinki. Klaggers is miles from anywhere for those looking to fly - there is an airport there but it’s a relatively small compared to the big international ones. A lot of people fly to Ljubliana or Munich and do a car hire or get a train but it’s still a bit of a faff.
we also drove there in 2007 with the motorhome and made a holiday of it by going to the Italian lakes after. as you say, stunning part of the world and a lovely venue, just the logistics of it might not appeal to those coming from outside Europe. Helsinki is a simple in/out venue in many ways.
