Boise 70.3 last June where I tore up my underarm so bad, I walked around like a bodybuilder for a week with my arms sticking way out to the sides.
I had tried some different lubricant methods for this race thinking perhaps the water portion of the triathlon would need something different. When I obviously found out those products didn't work, I went back to using a product I had always used and should not have differentiated from - BodyGlide. The very next weekend, I participated in a sprint distance triathlon in Park City and went back to using BodyGlide (as well as a homemade remedy of packing tape - don't ask.) As you can see, no chafing and a third place overall finish.
Graveyard 100 in March and my 350 miler on the Oregon Coast in April, I am going to need to think about chafing as little as possible. With so many other tiny aspects to worry about, I do not wish to even spend a moment of time wondering whether I am going to be bleeding from unseemly places again. I will be able to race with peace of mind knowing that BodyGlide has me covered - literally!
