June 2012 Naylor's Beach Tri

I did my first Oly without a wetsuit. Too cheap to rent or buy. Water was 64 degrees. I was certainly in the minority, but it was fine after the first 100 yards. 

I've made the suit investment since then... more for the speed than comfort. 

I am not doing this race. But here is my 2 cents worth.

Anytime it is wetsuit legal I wear one.

First it is faster. Just under a minute per 500 meters for me.

Second, more buoyant. You will almost float especially in salt water.

Third, warmer. I personally am a wimp in cold water.

Fourth, peace of mind that you can rest for a second or two if needed.

Fifth, no kicking and save legs for rest of race.

Sixth, protection form jellyfish or other sea creatures.

For Olympic distance l would guess 2.5-3 minute saving. Maybe 15-20 seconds to take off. So net saving of over two minutes.
