Running On Empty Production Stills

Setting off on the trail at sunrise in the town of Cadenza.

Bosio takes a break to lubricate legs, rest and to consume much needed calories during the middle of the attempt of the GR20.

Logs of distance, check points and times along the trail.

Support crews traverse the island along highways and meet at checkpoints where the GR20 crosses the roads. These become rest points for Bosio to eat and rest before setting off to run through the night.

Power naps are essential to surviving a 50 hour run across 120 miles in the mountains of Corsica.

All smiles at the conclusion of the 120 mile trail
