Check out the kid on the right... that's the universal sign for "I've cracked!"

My son told me after the race that he stayed with his sister's group as long as he could, but when he couldn't hold their pace anymore he worked with this kid knowing that if he could hold on over the final climb he could outsprint him to the finish. Sitting at the finish line it was so cool to see them crest the big climb and then about 300 meters from the finish he darted out from behind the other kid and put the hammer down!
