Sentiero 4 Luglio SkyMarathon (SkyMarathon 4th July Footpath) is a skyrunning event created in 1994 at Santicolo di Corteno Golgi by Giacomo Salvadori.
Its main claim is "a real stairway to the sky".
Three times trial world championship (2003, 2004, 2007), for a few years (1999, 2011, 2012 and 2013) was organized in collaboration with Aprica (SO); from 2014 is again organized only by Corteno Golgi (BS).
It consists of two distances: classical marathon and half marathon (this last, since 2000).
