Climbs are excellent places for a single rider to try and break away from a bunch, as the lower riding speeds in a climb seriously reduce the drafting advantage of the bunch. The escaping rider can then further capitalize on that rider's position in the descent, as going downhill alone allows for more maneuvering space and therefore higher speeds than when in a bunch. In addition, because the bunch riders are keeping more space between them for safety reasons, their drafting benefits are again reduced. If this action takes place relatively close to the target (e.g. another bunch ahead, or the finish), the ride over flatter terrain after the descent is not long enough to let the drafting effect (which is then working at full power again) make the bunch catch up, making a climb escape even more attractive.
