a route that is
strenous the climber may "run out of steam"
before the end and fall off. Having to place protection
whilst climbing greatly contributes to
When in doubt run it out indicates that
if you think you might fall
off then don't bother placing gear, just try to get
to the top. Not normally a good idea, but if the gear
is going to be crappy, then perhaps this is an option
to be considered.
This is a favourite expression of Ben Moon's
but he is a climbing god.
