Set in the heart of the Valais Alps, Sierre-Zinal is an extremely demanding 31km race, with a 2200m ascent and a 1100m descent. The exceptional scenery, warm atmosphere and impeccable organisation explain the success and longevity of Sierre-Zinal. As Jonathan Wyatt wrote.

What's more, it's considered to be the oldest major mountain race in Europe.
