ok...a couple of your comments are a bit outrageous. I'm doubtful about the 5:30 pace and 220bpm...it would be sufficient to say that he was racing very hard. But, I'll cut you some slack ;)
Either way... to all the people saying he should have altered his course or stopped, or slowed down: She literally went from the side of the road to the middle in less than 2 seconds. I'm very, very doubtful he had much of a chance to even think about moving more. Plus you have a runner coming towards him in the other lane. The fact is, if she takes one more step backwards she's getting T-Boned. People are making the giant assumption that he was paying attention to her to begin with. Perhaps he didn't notice her until she started moving into him (literally less than 2 seconds).
People calling that a punch are just being ridiculous. He may be the 2nd coming of Kevin Moats...but, I'm giving him the benefit of the doubt since 99.9% of the people I've met in this sport are good people. I can also guarantee if I'm running full tilt and put my arm up to fend somebody off from walking into me in a race the person on the receiving end at most triathlons is going to lose badly. I'm not saying this to sound tough...it's just a fact. The dude exercised some possible bad judgement in the heat of the moment. The fact of the matter is, if she's paying attention AT ALL...then NONE of this happens. /serious-post
Next time...he should learn from Pedro.
