New Here from Central Ohio

Great, welcome! I'm from Columbus/Westerville.

There are lots of great races nearby - HFPracing.com has a ton, and there is also an OSU one and a few newer races.

Check out the Mentor Forum here at BeginnerTriathlete - you can get into a small group to encourage one another and ask questions.

I'm glad you found us!

I asked to join a mentor group! I'm in Orient, just south of Grove City. Where can I go locally to find tri-suits, wet-suits etc.?

Tri-Tech Multisport on the north side is the only place I can think of to get everything centrally. They are kind of a high-end shop and in the past I've heard complaints about a kind of snobbiness there.
There are lots of bike shops and running shops around. And you can always get wetsuits online. If you become a Performance member here on the site, you'll be eligible for some discount codes at XTerra and other brands.

Just worried it won't fit. I guess I could always send gear back for exchange?

Yes, and with wetsuits they always have very specific size charts. You can get someone to measure you, and it should produce an accurate size for the order.
