Which one sounds most exciting to you?

I did a sprint tri first, assuming I would walk the run portion (which I did) and putt-putt through the swim (which I did). My goal was just to finish, and I reached my goal. It was a tremendous feeling of accomplishment, and I proudly considered myself a successful triathlete.

Think about your goals, and what will give you the juiciest sense of accomplishment.

For example: do you like the idea of pushing yourself as fast as you can and going all out through every leg? Maybe consider the try-a-tri. Or do you like the idea of going long and pacing yourself with distance as your goal and speed as just icing on the cake? Maybe consider the sprint.
