Can't speak to the accuracy of this, but the article I saw said it was an African antelope known as a red hartebeest. "Red hartebeests, a type of antelope, are among the swiftest animals in Africa and can attain speeds of 65 mph."
When looking closely at the slo-mo portion of the clip, it appears that the animal lowered its head and actually tried to use it's antlers to attack the rider. I wonder if it may have been an intentional attack?
A coworker of mine recently wiped out in a cross-country bicycle race and broke his femur. Has been out for several weeks, just got back last Thursday. As soon as this video came out, the joke went around that the person behind Larry got video of his wipeout...
Yep, it looked deliberate to me. Obviously a new terrorist threat. I can see additional screening will be added to HomeLand Security's list....No Deer, Antelope, or Gazeles with antlers.
