Oregon steeplechase runner Tanguy Pepiot learned a very hard lesson about showboating this past weekend: just don’t do it. Ever.

As he was running up to the finish line at the Pepsi Team Invitational, Pepiot started celebrating his victory a bit too prematurely, waving to the crowd, thinking he had the race in the bag when he got a rude awakening.

Washington runner Meron Simon saw Pepiot slow down, preening to the crowd and saw his opportunity. He sped up and ran through the finish line, beating Pepiot by .10 seconds.

Pepiot couldn’t believe it. First, his face registered confusion, then, inevitably, devastation when it sunk in that his hubris cost him a win.

Life sure does come at you fast.

"I thought I was by myself, like, far in front of the second guy," Pepiot told RunnerSpace. "I saw him (Simon) on the screen, I tried to pick up, he just got me on the line. I'm not proud of myself right now, but it's a good lesson for me, I think, not to do this in the future. Next time I'll just run the whole final stretch and celebrate in the victory lap."

Lesson learned.
