Sprints are a great event for first timers.
Just make sure you train for it.
The biggest mistake that I see beginners make is to train with the full distance. So that means that they go to the pool and swim an 800 straight, just like on race-day. Next day they do a 20k bike ride... and the day after they do a full 7k run.
That doesn't work well.
What's MUCH better is to do something like that once to be mentally prepared... but then train with intervals. That means doing something like this for the swim training: 8 X 100m free + 6 X 150 Fee + 4 X 200 Free mixing in some sprinting w/ lots of rest and some touch-and-go intervals at 90% effort with little rest... and calling that a day instead of a long long workout.
The biking and running should be approached similarly.
I've seen so many beginners show up and totally bonk because they did lots of long distance sets that mimicked the distance of the race... and thus were prepared for the distance, but not for race day. There's a big difference.
"The worker has the right to leave his boss, but can she do it? And if she does quit him, is it in order to lead a free life; where she will have no master but herself? No, she leaves to sell herself to another employer. She's driven by the same hunger. Thus the worker's liberty is only a theoretical freedom, lacking any means of realization; an utter falsehood."
