The history of the Jizerská 50 dates back to 1968, when the first race took place as part of winter preparations by mountaineers for their upcoming season. When some of the race’s founders set out for their mountaineering exhibition in Peru in 1970, they had no idea of the fate that awaited them. Fourteen members of the expedition lost their lives in a rock avalanche on Peru’s Huascarán, and a fifteenth member had died a few days earlier. Since that time, the race has been referred to as the Peru Expedition Memorial, and a remembrance of the climbers has become an integral part of the ceremonial opening of the Jizerská 50.
