Different distances and difficulties for all ability levels. Mountain Marathons in the most spectacular mountain environment in South America, on pre-Inca trails, through ancient cloud forest, along rivers, past lakes, over moraines with the most awe inspiring scenery. The race was dreamed up by our founder who, after running 5 of the big Peru Ultras, realized that the best trails and scenery were in his back yard. He thought that it would be selfish not to share it.
