Rewarding Experience

Great event with a spectacular route, absolutely breath taking to be on the road at sun rise

Breathtaking

One of the best experiences we’ve had. Stunning scenery along the route with some tough climbs and challenging navigation. All of which made memories for life. The camaraderie from other teams that passed and were passed along the road was pure class,each one having the same experience,not competitors,but allies encouraging one another on.
It certainly lived up to its reputation.
