If you think about it, a tri is just a single TT where you switch equipment a couple of times. The activities are somewhat different, but the philosophies are the same. Make yourself a Prius and become as efficient as possible. It's all laid out in front of you. You are in control. Just hit your numbers and all will be well. About a mile into the bike leg, I'm usually thinking, " This sucks! I just did this same $hit in the water." Then I get to the run and think, "Great, more of the same. Boring!"
By far, the most fun I've had in endurance was the Urban Athlons I used to do in Chicago. Tough Mudders without the mud/water. Run for a ways then a different set of obstacles/situations to conquer. That 8 foot wall at the end you have to get over to finish and get your bling. That was fun. Unfortunately, my brother moved and the event became a Tough Mudder or Spartan in the countryside.
