Really, anybody who is jumping should build up a strong enough leg to be able to do that! Not to diminish her talent or effort, it's just something we should all aspire to. What a round! I just hope that she was actually finished with the course before she left the ring and fell, so that it all still counted!
Her cool head is to be commended more than anything ... she took some pretty serious bucks, lost her stirrups, and just kept going like nothing happened.
