A waxing moon floats in the pale blue dawn just above a horizon of rolling green hills that mark the edges of a wide valley. At first, just a murmur in the earth, barely perceptible, a shudder that wrinkles then quickly becomes thunderous. Three dots swell larger and suddenly they are upon me, towering creatures with hair to the ground. In an instant it is over.

Horses and yaks prepare once again to race down the corridor between the hills, flanked by delirious onlookers who will joyfully roar. Four flags – green, red, yellow, and pink – flap gently as they mark the entrance to a large white tent with dark blue borders. Scores more are covered in propitious shapes and patterns, most noticeable of which are bats, considered cunning and extraordinary in China for more than a thousand years.

When I climb up one of the bordering hills and look down into the valley it seems an ancient army has encamped. Dozens of tents are in symmetry with each other; horses and riders with their arrows and bows at the ready congregate on one side of the camp, while those to be conquered – the hearts of spectators – on the other. The next race is soon to begin and the excitement is palpable. Thousands of Tibetans have gathered to watch.
