Do you have an open water swim mask or goggles? I wear goggles when I work out in the pool, but I was able to buy an "Aqua Sphere" swim mask the day before my race and it was WONDERFUL!

What you have to wear sounds perfect; you might want to swim in it once to see if there are any problems (there shouldn't be) and to see how it feels.

Have you cycled and run together in one workout? Since it's close to your race, you may not want to do it for a long distance, but it might help you to get a feel for T2.

I know you'll do great - just take it easy and enjoy the race!
