sunblock

x2 on this, although I get the CVS generic version. Very light, doesn't clog up pores, and it's lasted me 4-5 hours on a day when I lost 7 lbs in a 4 hour ride (Including drinking close to 100 oz of fluid). I have yet to even come close to getting burned when using it.

Same here.  Works really well.

Target or Coppertone sport spray.  By mistake bought the 30 instead of 50SPF.  Did a 4hr ride (full sun) on Sunday and was fine (except for the couple of spots on my back that I missed.....ouch!).  I'm fair/reddish hair and burn easily and sweat a ton. 

Still looking for something sweat-proof for the face that works well without repeated applications and doesn't cause breakouts. 

Took my kids to the local pool for a day of fun between 11:30 and 3:00 pm. Like an idiot completely neglected to sunblock my back...after religiously ensuring the kids were wearing full body bathing suits, hats, SPF 45 on anything not covered.

My back got so fried that I had to cancel my ride for yesterday. The thought of the heat beating down on my burned back (even througgh a jersey) and rubbing with sweat kept me home....and lesson learned for this summer at least!

I also use Bullfrog.  I burn easy.  I can put this stuff on before the swim at an IM and not need to re-apply anything.

It is alcohol based so you aren't left feeling greasy after applying it.

Perhaps you have a chemical reaction to an ingredient found in the Banana Boat product?

I fry no matter what kind of sunblock I use; it's a matter of frying vs. frying less. For me, Neutrogena Sport has been mediocre but will do in a pinch, especially if I reapply it a lot. Coppertone Sport works better and doesn't run into my eyes and sting (Neutrogena does), but it's still not great. The Banana Boat lineup, including the newer spray Sport varieties, have been near-useless for me.

I'd love to try Bullfrog but we can't get it here (the Neutro and Coppertone I brought back from the U.S.).

There is one non-frying sunblock which a friend of mine makes here. It's also edible and smells like chocolate, which means I keep wanting to lick it off myself. The one problem is it's not rub-proof. It is incredibly sweat and water resistant without making me pour sweat additionally or causing me to break out, though.

I've tried pretty much everything, and for the OP and others, the sport-specific formulations of Neutrogena and Coppertone are at least worth trying.
