If either one of these guys slow down a bit... I'll be on their bones as quickly as a snapping turtle !!~~!!

shorts
 

Speedos for running are excellent -- though when I was a runner I always wore running shorts over the speedos. These were the pre-90s style, which today would be pretty skimpy. But the speedo underneath provided the right amount of support and let me feel comfortable too. Plus it's what got me into wearing speedos at the pool!

The Winner
 

And the winner is....

winner
 

:) Wow - neat fit indeed (and curious about the tat)

Holy cats, he is awesom and his suit looks wet, (or shiny) to bad you cant see the logo or brand, if sdi i would of jumped on my computer and try to find the same.

Goggles
 

OK nice suit ... but running in goggles? Totally uncomfortable!

interpretation
 

;) Well, the thread says running and not runners and a competition swimmer might well have to run in bare feet and with rubber cap on, as well as speedos and goggles, if he finds himself late at the starting block.
Then again Louis thinks he is already wet so maybe the outdoor pool water was cold and he needs a quick warm-up ?

another idea
 

Maybe a triathlete just out of the swim session and running to his bike.
(is there a number on his leg ?)

I run on the beach in a speedo then I can jump in the water for a swim if its warm enough. Sometimes I ride the bike around the beach area in a speedo.

Agree with Byron, triathlete on way to the bike leg... I am guilty of leaving the googles on until I get to my bike, as well. Regardless, this guy is pretty hot.
