first tri coming up...man question help?

I went with tri shorts (from TriSports.com - use the begtri coupon code!) for all three legs, and a running singlet for the bike and run. No problems during either transition. I'm looking to get a one piece tri suit for next year's races, but the shorts were only ~$42. Most of my biking (commuting) is done without bike shorts, so having that pad was wonderful for the ride!

You could wear a swimsuit and change into bike shorts, but I'd hate to have to run across the transition point to a changing room or portapotty and then try to find my bike again.

where is this coupon code located?

At the checkout portion, there will be a spot for coupon codes. I think it's before you enter your CC info. You save 15% off your total purchase, and BT gets a small kickback, too! I haven't had any funds to donate to Ron yet, but I've made all my purchases through them with that code. They're very good, service is excellent, shipping is great. Just watch the product sizings: the Desoto singlet is a 'small' large, I should've got the XL, but the shorts fit perfectly for my frame.

I wear Jammers (thigh length speedo) for the swim, then in the transition I pull on bike shorts and leave them on for the duration.  The lycra is dry in moments and is form fitting enough to avoid chafing.  I've don't this for two Olympics and find that it is very comfortable and efficient.  Takes about 5 seconds....

I wear my swimsuit w/ my bike shorts over them...but i also have 2 tri outfits that i also wear...I usually don't change from the bike to the run as the bike shorts were suprisingly comfertable during the run for me.
