Question

I'm confused and don't know whether to go through route 16 or 11 and i don't know where to train for the lvl 60 trainers in route 11.

Answer 1

You can't reach the Level 60 trainers until AFTER the Elite Four. So the best place to train before the Elite Four, Victory Road is your best shot.

i meant after the n's castle because the trainer at route 11 are level 60 and up

Answer 2

What Mew said... also you can train on route 10. Run around in front of the grass until you see a patch shake. The Audinos there will give you 2000+ experience!
