Rescues from multi-pitch climbs are far more serious, and climbers will use additional protection to avoid this.
[1][2] Multi-pitch climbs are usually done in teams of pairs, and the position of leader can alternate between pitches or after a group of pitches (called "block leading") as long as both climbers have the skill and competence to lead on the route.
