100% do it. Ride the whole course. Dont go swim at lost lake, swim in Alta. Thats where the race is. Bouy line to follow, then ride from there. Swim / riding / running the course should pay off huge come race day. Swim it at the same time as the race to know how sun will effect your sighting. Ride it to see the hills up and down. Know when you can mashit cuz there is a downhill for recovery coming. Ride and run at the same times as race to feel heat and winds. Roads are fine and MOST drivers are cool..even the loggers, just give'em a shaka, thumbs up, whatever. I have found karma pays off.
