Many of the best climbers competed at the Edinburgh World Cup this year. The sport will be featured for the first time at the 2020 Olympics.

The Edinburgh International Climbing Arena, which hosted the event, is one the largest indoor climbing centers in the world.

Climbing routes are designed to be spectacular for audiences, as well. At the Edinburgh Wold Cup, they gasped and cheered at some of the daring feats.

Speed climbing may be the most fun to watch as the athletes frog-hop and monkey-climb a slightly inverted wall nearly 50 feet high in less than 10 seconds.

During an "observation," climbers get their first exposure to the route. For blind climbers, their guides act as eyes for them as they plan their strategy.

Communicating by headset, guides describe to blind climbers where their feet and hands are in relation to a given hold.

The climbing arena is an adult playground just outside the city of Edinburgh housing various climbing walls, a rope obstacle course and a cafe with large observation windows.
