2021 Akagi Trail Race feature image

Akagi Forest Trail Race | August 22, 2021

More cross country running than hardcore trail running, runners will enjoy spectacular views of the vast Akagi forest throughout the course. Runners can opt to complete one loop on the course to clock in roughly 13KM, or to run the same course in reverse for a total of about 26KM.

Out here, the summer heat is less brutal – enjoy the refreshing and cool breezes as you race your way to finish the Akagi Forest Trail Race!
