A unique experience

“The first edition of Puerto Vallarta México by UTMB® will take place at one of the most representative areas of Mexico covering Mexican land and spirit at its purest. Runners will find all kinds of terrain and weather, from steep technical climbs and downhills to the complex muddy single tracks of the jungle and agave fields, broad paths and so many different ecosystems."
