As I started indoor climbing this year I would like to know what distinguishes it from outdoor sport climbing, especially when you are lead climbing.
I know that there are huge differences in safety, like outdoors
- there aren't always bolts available as belay points (like indoors) so we need to use the less safe cams/friends, nuts, ...
- bolts might be insecure
- stand isn't as stable so we should belay dynamically
- bigger falls because of less belay points
This list isn't complete.
What could you add to this list of safety concerns?
Besides from safety, what are major differences between sport (indoor) climbing and rock (outdoor) climbing?
Are the difficulties comparable to indoor scaling systems?
As for the last point I can think of tougher conditions outdoors (again safety issues or strong wind, wet rock, psychology aspects and so on) and pure length of the routes. Besides that, I guess an indoor UIAA 6 should be as tough as an outdoor UIAA 6.
You are right guys, the question was too broad when asked about comparing sport to trad climbing.
Why do you still think, the question is too broad, comparing bolted indoor sport climbing to bolted outdoor sport climbing?
