I'd say the game has just about begun for real in your case. If you explore everywhere and do most side missions there should be quite a few hours of gameplay left!
As for the runners, they usually come back after zoning out of the tower and back, at least they do for me. To equip them, just talk to your trainer and smith about it.
Remember the tower stone (shortcut U), it lets you teleport to the tower, and then back to where you were again. Handy!
Edit: typo - on the shortcut
