The guide showed us how to attach, walk and un-attach our lines, and after practicing a couple of times we were ready to go. I’m not a fan of heights, so climbing to the top of this 52 meter arena felt slightly uncomfortable.
Just so you get the idea, The O2 is a massive dome with a blue walkway suspended above the dome. The surface of the walkway was soft and unstable. It’s a bit like walking along a trampoline, and it took a few steps to get used to the instability of the path and the bouncy feeling. Regardless, we felt incredibly safe as we were attached to the safety rail the whole time. Using the harness and climbing gear does take some getting used to, but it’s not really that complicated and after a few minutes we were climbing like pros!
The first section is the steepest with an incline of 28 degrees, but after the climb flattened out, we were treated to the most stunning views of London from every angle.
