This course can be hellish in August. The beginning will be hot. And the South Side of Fuji will be hot -- even at 1400 meters. And Mikuni Pass has very little / no shade and is crazy steep and crazy hot. 4865 meters of elevation gain over 234 kms.
I've ridden almost all of this at one time or another. And cannot wait to do it again ... but not in August. Fall or Spring.
