Then take your time in transition and change into warm dry clothes. No one is forcing anyone to sprint out of the water, do a flying mount onto your skinny tire death trap and ride sockless in a wet, sleeveless trisuit.

I don't see this race as being one of the mass market downstream swim, flat bike 'everyone's a winner!' bullshit races that people do to one-and-done or set some new PR. I gather from the marketing that they are catering this race more to the 'extreme' triathlon crowd, it's supposed to be hard and the environmental conditions (altitude, temperature) are a deliberate part of that.

Not to say that this race really compares to Norseman, but you don't see a people there complaining about the cold swim, weather or possibly sketchy roads. That's kind of the whole point and the reason they all signed up for it in the first place, to overcome adversity. I don't know how hard this race will prove to be, but I hope people had sense enough before signing up to realize that a race at >10,000ft in the rocky mountains in September might not be all sunshine and lollipops.

edit: to clarify I'm not directing this at you personally, more the general vibe I get from this thread. Some sort of warming / changing tent in transition would be great if they could swing it, but I'll be bringing some extra towels just in case.
