St. Michel Church in Chamonix marks the start and end point of the Mont-Blanc summit attempts. The Church Summit to Church Route has been first attempted in 1990 by Swiss, Pierre-André Gobet. His time 5h10m14s was a long lasting record.
Since then, many alpinist, trail runers and ski-mountaineers have trained on this route, that became a popular challenge, in an attempt to beat Gobet's record but without success.
Some have attempted both the ascent and descent while others have chosen a one-way route. The descent is much more dangerous than the ascent in any summit attempt and Mont-Blanc makes no exception.
Speed records have been set on foot, bikes and paraglider, though the skis and paraglider records include a bike component. However, some records may include a combination of climbing and running in any of the discipline one choses.
