Sunscreen

Good advice above. I use bullfrog in the spray. I know the sunscreen experts frown on a spray because they are afraid you will inhale the aerosol but for petes sake I am single and I can't get those hard to reach places well!!  I am not a red head but I am pretty fair.  Bull frog never lets me down.  I spray before the swim and before body marking.  I am usually good to go for Oly or a sprint. For an IM I re-apply before the bike.  Spray is easy to apply esp on your neck.  I spray it into my hand to apply to my face. Squirt squirt you are done.  No pesky cream to rub in.  Most of the creams are too smelly for me and make me sneeze like crazy

For both of my Ironman races, I've switched to full bibs and a regular bike jersey in T1.  For Vineman, I also had arm sleeves that I wore on the bike and first half of the run.  I'll probably do the same for B2B this fall.  

I like the Bullfrog sunscreen as well, and will put that on my neck, ears, and face when I ride.  

I never wear a tri kit for bike/run workouts because my shoulders/back burn... but with this it could be possible.  any advice on sizing?  the product is unisex and I typically wear a mens small in all things triathlon/cycling. 

You can just wear those sleeves, or a long sleeved shirt / jersey under your wetsuit, if the race is wetsuit legal.  They dry out pretty quick on the bike.  See my avatar.

There are a few things about sunscreen that a lot of people don't know about - I know I didn't until recently and I'm very fair and live in Florida, so sunscreen and I are friends!

First, and most surprisingly, reapplying doesn't let you stay in the sun longer.  The reapplication is only to maintain the effectiveness of the original application, it does not prolong the amount of time you can stay in the sun.  For example, if the sunscreen provides 180 minutes of protection and you reapply at 120 minutes you still only have 60 minutes left of protection.    

Most people use too little product.  For an average sized person it is recommended that you use 1 tsp per limb and half that amount for your face and neck.

Sunscreen takes about 20 minutes to soak into the skin and become effective.

To know how much time you should be protected, multiply the SPF number by 10, eg, SPF 30 provides 300 minutes of protection - but reapply often!!

It would likely smudge it.

I was a body marking volunteer at Kona twice and when they were giving us the directions on how to apply the numbers, they said that if you make a mistake and want to remove it, use sunscreen.

Neutrogena Sport 75 or 100 SPF works great for me - I use the cream on my face and the spray on my body. It's lasted me through 6 and 7-hour intensely sunny bike rides before. 

I also have a pair of the Cool Wings, those are really great. They feel fantastic when they are wet! In my last IM I had them in T2. I carried them for a bit and then pulled them on while running in the first mile - I didn't want to do it standing still - this worked out pretty well. I would have worn them on the bike but I had arm WARMERS for the first half. Yes warmers for the bike and coolers for the run!

ordered some cool wings.  i had no idea such a thing even existed before this thread. 

I have also used an under armour heat gear long sleeved shirt under my tri shirt for long rides.  If nothing else it keeps the sun off my arms and back.  For some reason my legs never burn.  I have trouble with my face because I sweat so much. I put it on in the am before leaving for my ride to let it soak in

I second Lisa's Neutrogena suggestion. Great for sensitive skin and it is all I use on my face. Like others, I am training in Florida, so sunscreen and arm coolers are important gear.
