Crane, one of the UK's top female boulderers, has previously climbed Font 8A and described her efforts on Zentrale Traverse:

"The weather was so poor I didn't even know if there was any point in putting my boots on. It was raining on and off so all the top-outs were a no go. Instead I took to a traverse, very crimpy but surprisingly my style. I warmed up on the start and worked the middle and end moves for half an hour or so. They were hard but do-able.

Having had a rest I pulled on for my first attempt from the start. The start and middle went easily but by the end my fingers were numb and my hands stopped closing quickly. I stared at my fingers to stay closed and managed to do the hard mantle at the end which I hadn't actually tried, so I guess I got lucky!"

The Sustenpass boulders are a set of superb granite blocks in a beautiful alpine setting in Switzerland. You can read more about the Sustenpass Boulders and see a photo gallery in the UKC Logbooks.

Zentrale Traverse is graded 8A in some topos such as the Blocheart guidebook and is graded 7C+ on some websites such as 8a.nu.
