Excited

I'd say get in a pool and just start swimming. Of course it partially depends on how much experience you have had in the past. It definitely helps and is a good idea to take some lessons or join a masters group. Technique is very important with swimming and can make it much more enjoyable, efficiency is key! As far as the speedo, its not necessary in training and I'm not sure if you are talking about the knee length or the brief. Most guys wear the knee length speedos. And as far as shaving you definetely don't need to do that. I guess some of the pros probably do it for swim and bike AERO but it will have no affect on your time. lol Good Luck on your training!

Do you know someone who is a decent swimmer? Have them check out your form and get some tips. If you start with bad form, you will see much slower progress in your swim.

As for speedos, I wear the knee length jammers. They are much more comfortable.

Best of luck to you in your training.

Dont worry about shaving for now. Get some help with swimming.
