In reply to Removed Usercalixtus06:
If you don't know how to do this then my advice is find someone who does actually know to show you how (and don't listen to any advice here).
While the theory is very easy to explain to experienced climbers there are many safety points that are not easy to explain on a forum like this and the consequences of getting it wrong are quite severe.
If you are an experienced climber then your basic options are:
"Safe methods"
- rig from the top if you have safe access
- clip the top anchor from the ground (short route or long clipstick)
- use a responsible child (with or without an ohm or ground anchor as appropriate)
- borrow another adult belayer to help you get to the top
- ask another climber to set up the top rope for you
"High level of skill/competence required to be safe"
- solo the route and set up a top rope
- clip up the route using a clip stick and set up a top rope
- self belay the route and set up a top rope
Assuming you can't use the first set of options you're in the realm of substantial risk and need to know what you are doing and have more than theoretical self-rescue skills because you need rig the TR anchor and get down safely. Not for the inexperienced really.
Once you have one TR set up it's quite normal to access the next route sideways from the top if the routes are close enough and anchors are suitable. As with all top roping you should protect the lower off from wear which gives you the additional problem of how to remove your gear from the top on your own.
