What's the experience per hour at the wilderness agility course?

I have managed up to 45,000 xp per hour. I guess you could do more with energy potions and / or familiars.

Ok.

 

 

 

I'll be using a terrorbird with scrolls.

If you pay full attention, with your terrorbird and/or super energies, and get lucky enough not to get any revenants, you might be able to get around 50-55,000 experience an hour. Once you hit 70 (if you continue training), I recommend doing Ape Atoll with summer pies and Super Energies.
