What to wear for a beginner?

Hey!
What I do, Is I wear my spandex Lu Lu Lemon bike shorts over my bathing suit (you'll most likely look funny, but it works!!), that way I just jump into my bike shoes and I'm on my way for the bike. Then because I don't have a number belt, I'll have my run number pinned to a shirt, and when I get back from the bike, I'll put on the shirt while I'm running.

What I've seen people do, is wear a sports bra under their bathing suit. It won't slow down your swim or anything, just gives some extra support.
Also, wearing the shorts over the bathing suit is a bit more comfy than just a bathing suit.

Let us know how your Tri goes, and have fun!!

I am fairly new to triathlons also. Currently I am just focused on finishing and having fun.

I wear a racing 2 piece for the swim-a sports bra for the top-but not white. I pull my bike shorts and jersey on over the suit and run in the bike shorts.

If/when I become more competitive this will change-it is hard to put bike shorts on a damp body.

Great! All wonderful suggestions!  Thanks for all the help!  I'm going to try and work with what I have.... and I too have the LuLu bike shorts... I love them!

For my first one, I bought a pair of tri shorts and wore the top of a two piece swim suit.  In transition, I put on my bike jersey and bike and ran in that.

You don't have to have specialized clothing.  If you are planning on putting more clothes on, make sure to practice this while you are wet!  It's a challenge and some things will work better than others.
