Has anyone done this race in Switzerland? Just noticed it via a random Google search, noticed i'm still in time to register, and am planning a holiday just down the road for the 2 weeks around it.

Looks like a pretty tough mostly uphill affair, it mentions running on pretty good tracks (which I was expecting) but also mentions the glacier.

Just wondering if this is the standard sierre-zinal type effort with some rough terrain higher up or something a bit different?? Got some microspikes if those are needed.

Any info at all on this race would be most appreciated as it sounds great but want to be clear on what to expect before I end up in over my head.
