I did the full IM there in 2011 and it’s a stunning course. We flew into Vegas, stayed there for a few nights and drove up. It’s less than 2 hours easy drive. There seems to be plenty of hotels in the town, but it’s a slightly strange place (very Mormon😉).
Have they announced a date for it? The IM was the 1st week in May. The water was very cold (14C) and they let people wear booties and gloves for the swim. It felt quite cool for the beginning of the bike, but it got hot very quickly. I think it was in the 40s on the run and the original IM run course had 800m of climbing on it, so up and down the whole way. I think they might have switched to a flatter run course more recently. People were talking about the effect of the altitude 1-2000m above sea level, but I don’t know whether that’s high enough to have an effect or not.
I guess the championship race would be in autumn, so the water would be a bit warmer and the daytime temperatures might have fallen a bit.
I’d definitely consider going back for the full IM, but can’t see 2020 working for me, so maybe a long term goal for 2023😎
