Touring usually means very long multi-day (or multi-week) rides carrying a lot of gear (camping, cooking, clothes, etc) on the bike. Can also apply to unloaded/creditcard touring involving using hotels/motels instead of camping.
Typical touring questions might cover:
- How to carry everything
- How to carry less stuff
- On-road maintenance with no shop access
- food/water for a long ride
- picking a bike or components
- figuring out routes
- Issues surrounding very long rides
