That fall right at the line was a bit scary. I thought he could have hurt his knee. I'm not sure who thought ice-slick concrete was the best finishing surface. It was nice to see him bust out a few push-ups before walking across the line though.
I'm not a fan of showboating or theatrics during any portion of s race. I wish he didn't fall, but that caused his fall. Run during the race. Do the other stuff after.
