run a triathalon

I think that if this goes the way I think it will this will escalade into running a half Iron man Tri.. Utimately to a full Iron man Triathlon. but lets tackle the little one first

but first i need to learn how to swim and ride a bike.

although, did you know that duathlons exist? maybe i can just focus on doing one of these instead?

Start with a small distance triathalon and work your way up. Make sure you spend lots of time in the water over your head especially if you never have before. It will give you the confidence to swim with everyone around you.
