TDS

It is believed to be the first death in the 19-year history of the Ultra-Trail du Mont-Blanc races in and around Chamonix.

A year after Hillary Allen rehabilitated from a devastating fall, she had to recover from another major injury and the darkness that came with it.

Trail runner and filmmaker Andrew Drummond set out to capture TDS, the epic companion to UTMB, and came away with these scenes from the race.
