WHAT AN AWESOME, BREATHTAKING, SCENIC AND SERIOUSLY CHALLENGING COURSE !!! YOU SHOULD HAVE SEEN THE HILL THEY THROUGH IN THE MIDDLE, WHEN THE TARAHUMARA RACERS HAD TO STOP AND WALK SOME OF IT, DAMM !!!!!!!!!!!!!! IT WAS A BLAST AND AN HONOR TO RUN WITH THESE RACERS FROM MEXICO. I FINISHED BETWEEN TWO OF THEM- THEY WERE 2ND, 3RD, 5TH, AND 7TH IN THE 10K. I STAYED RIGHT IN THE MIX. I WAS ONLY THREE MINUTES OFF OF THE WINNER, 16 YEAR OLD COREY LEWENKAMP FORM WESTCLIFF.
