I'm glad you posted that.  Last summer that happened to me.  I still have a discolored band on my lower back from riding for about an hour.  I am naturally quite pale and am serious about sun protection.  This area had not been exposed at all so I had blisters in that area. 

Hope you feel better soon.  Sunburns really hurt.

jami

been there..... done that.... won't do it again!!

2x

Also, if you have a shaved head (short hair, or no hair) and are out, make sure to spray the top of your head. I am dealing with a fried head after this weekend.

This is part of the reason I'll be training in biking kit this year.  Bibs and a jersey will keep this from happening.

Been there, done that, it sucked

I have a permanent sliver of tan on my lower back.......NONE of my bike jerseys are long enough and there is always a space between my shorts and top that gets exposed to the sun. 

I've been there too and won't ever forget it again.  Ouch! 

I did 3.5 hour brick sunday & wore what I plan to wear in my 70.3 in 3 weeks and put suntan lotion on and as I was about to leave had my 11 year old get that spot really well. I leaned over and told her to be generous. I have the strangest looking tan sliver.

Good reminder!

Until now, I did not know that the official name was "tan sliver"

I completely forgot about the slots for airflow in my helmet. Now I have strange patterned sunburn on the top of my head.

Cant wait for the leaves to come in so Ill be in the shade 90% of the time.

And if you spend 9-11 hours a week in an outdoor pool... there's no such thing as "waterproof sunblock". Get out at the halfway point and re-apply.

Mike, I'm just disturbed that you are riding around with plumbers butt for extended periods of time.  I'm glad I wasn't drafting off you

You and I both!  I have two days of stubble up there because I was afraid to shave the sunburn. 

I got that same tan/burn this weekend.  Lesson learned.

Yup.  My burn turned downright purple.

Based on your photo,  I would guess that sliver is about 8-10 inches high and wraps all the way around to the front

I wore two braids in my hair for a hike a few weeks ago... burnt my part, right down the middle on top of my head.  Not fun.

dblbogey beat me to it, but I do belive reading that the lady's burn is still prominent 5months after her IM race.

Yea, that's a dangerous spot.

Yeah. I wore supersport superwater/supersweatproof sunblock last week at the beach and got FRIED (and even without sunblock I don't usually fry). Couldn't wear a bra or pants (had to wear a very light skirt or sarong) for two days. I now look like a hyena as extremely dark/burnt skin is peeling off, leaving quite light skin patches underneath.
