Advice for the Tri in Cranbrook, BC?

Considering doing the Rocky Mtn Tri on Sunday in Cranbrook, BC as my first of the year.

I’ve no idea what to expect. My big questions are: How cold is the water and how is the bike course?

I’m guessing its “medium crowded” (200-300 people in the Oly tri?)

The race is close and inexpensive, so it’s really tempting. I want to camp within a 40 min. drive of the start: I should be able to find some place, right?

Thanks in advance.
