Be cautious of “grade inflation” in climbing gyms
Many outdoor climbing areas have a reputation for ratings that are relatively easier, or harder, than the generally accepted grade.
Red Rock Nevada? The bulletproof sandstone is sticky, the cracks eat cams, and the bolts are plentiful. You’ll probably feel like Superman and climb a grade or two above your normal level. (But, the climbs are long and committing and the rappels are prone to getting your rope snagged, so bring a headlamp!)
Joshua Tree California? Just about everybody seems to get spanked on their first day. Between the sharp rock that shreds your hands, and flaring cracks that don’t take gear very well, that “warm up” route can definitely feel like a lot harder!
Similarly, some indoor gyms have a reputation for “vanity grades”, meaning what they might call a 5.10 is really more like a 5.8 or maybe 5.9.
If this is the only place you climb, you may start to believe that your ability is higher than it really is. If you then head outside and try a route at this same rating, you may be in for a rude awakening.
To mitigate this: Climb at different gyms and get a sense of how the ratings vary on routes of the "same" grade.
On your first few trips outside, leave your ego in the car. Try routes that are a couple of number grades below what you think you can comfortably climb in the gym. Even if you can lead climb safely in a gym, try top roping a few pitches initially when you’re outside, and consider using a stick clip so you don’t deck before you clip the first bolt.
When making the transition from indoor to outdoor, it’s an important safety issue to have a realistic knowledge of your abilities.
Sure, you might feel like Superman in the "vanity gym", but wait till you try going outside.
