I was doing a sport climb recently where there was a pretty good distance between bolts, resulting in long rope runouts. Falling before the next bolt could easily cause a person to deck on a ledge. Luckily, no one fell at this point, but it was very precarious.
My question is: What are some techniques, as a belayer or climber, can you do to minimize risk of injury in a fall during long runouts? For example, if the belayer sees the climber falling, should they run back to take up slack quickly? I've also heard of the belayer standing on high ground so they could drop at the same time as the climber to take up slack.
Assume this is a sport (not mixed) route and no additional protection can be placed.
