tri suit vs tri short and tri top

It really depends on your body structure.

I have a tall torso, and my tri top keeps riding up on me during my run.

I'm thinking about getting a trisuit to prevent that from happening.

I have both.  I like the tri suit becuase it's one piece- my tri top rides up a lot.  The good thing about the trisuit is that it's one piece.  The bad thing about is that it's one piece.  It's harder to peel off to use the restroom during a race- it just takes a little more time.  But what you can do with a trisuit is unzip it and peel it down if you get hot on the run.   You can't really peel off a tri top like that.

It's all personal perference though.  A trisuit will feel really tight at first but you'll get used to it.

Do you have a local tri shop or one nearby that you can try some one and see what you're more comfortable with?  Or, you could always both and return the one you don't want after trying it on.  Just make sure to ask about the return policy.

Maybe it's because I'm short (5'1", because I never had that problem

I've raced both ways (2 piece and trisuit).  I think the benefit of the Trisuit is that it provides great compression on your body throughout the race.  No slowdown on the swim at all.  If you're wearing a wetsuit, it doesn't matter which way you go.

It will cost you some time in T1 to put on a top.  It's kinda personal preferance.  And a Trisuit will only ride up on you if your Trishorts do.  And if that's a problem...I can't help you.  :P

I'm all about the 1 piece.  You look and feel like a fast torpedo... Or in my case a bit like a sausage ... I reality though they just feel so much better on the body to me.  I like the feeling of everything being tight and a little constricting.

Actually, it really depends on how much you need to pee.  One pieces are a PITA for that.  I learned the hard way during a HIM last year.  Anything longer than a Sprint and I opt for a 2 piece.

I've got both the Javelin Trisuit and a Desoto TriSuit.  Love them both.  No riding up of the top, no rolling on the waist of the bottoms.  It's great, plus it seems to streamline me a bit better.

You'll love it I'm sure

I saw you ordered a tri suit

That is what I did too and have done  bike/run...swim/bike bricks in my suit and am totally pleased with my choice.  I hope you like yours too!
