My first triathlon of the season is this weekend - bright (er, dark) and early Sunday morning up at Ray Roberts State Park. Camping up there the night before too, so I don't have to drive 60 miles at 4am.
Just doing the sprint distance, so no big deal really - just a strong 90 minute or less workout. And with the water temp in the 60's and the air temp in the upper 40's, I will be in no danger of overheating. Just got to find my wetsuit. And maybe replace my 13 year old tri suit.
