Although I am not a runner, why would anyone cancel a race due to what was an unforeseen event. If this is the reason, then Crow Pass marathon race or actually, any race that take place in the wilderness should be ban forever. There is no point to this cancellation since it will make no one safer. I think everyone who race this thing understand the limits and risks that is involved. If that unfortunate kid fell down and got kill instead of a black bear mauling, would this race still be cancel???
