I can tell you about Saturday, the Silver is not much more than what Bronze are doing hence Charan saying its your easier day and Bronzes hardest.
Same route to Bushmans, means up the loooooong Welcome/Belekomo pass.
From Bushmans to Roma it looks like Bonze go around via Pressure Cooker and you will probably do "Boilers" or "Middle Pass" . (If I read that map correctly)
And then this Foxhole/Freefall opfok.
I can see how this is going to be a long ride and keeping moving is going to be the key to klapping the km.
