Ticlio Pass (also known as Anticona) is located approximately 150km northeast of Lima, Peru. Starting at sea level in Lima, the road climbs at a gentle 3.5% average gradient all the way to 4,818 meters. The final 50km average 5%.
Ticlio is probably a 10 hour ride so I would start around 5am. I'll also need to know more about weather patterns and traffic congestion. Hopefully, its not a major trucking route. And finally, I also need to know where to finish the ride. Once at the summit, it appears you have a choice of roads towards the northeast and southeast.
I thought that Letras was the world's biggest, even after quite some research. But I found several Andean climbs last night that appear bigger. The problem is finding specific data on any of these roads. The best sources for finding and validating Andean climbs are often a combination of Google search, Wikipedia, blogs, BikeRouteToaster.com and topographical maps.
I will add other Andean climbs to my bucket list on this blog over time.
