The Cent Cols Challenge: As you begin to take in everything the mountains have to offer, you lose track of your normal life back home.

Rapha Ambassador Sarah Hammond won the inaugural edition of Australia’s Race to the Rock – a 2,300km unsupported race from Adelaide to Uluru – and was the only person to complete the course.

At first you try to avoid it. The circumstances are just right: 15 degrees, dry roads and surroundings in blossom. All those hours in the basement will now prove themselves worth it. Time to go outdoors.

It’s not possible. 100 mountain passes in 10 days. 200km a day with 5,000m of climbing. Let’s talk over drinks first before deciding anything… Who are the guys riding this? What is driving them?
