Another important role in climbing is that of attacker or counter-attacker. Climbing specialists use their superior abilities either to attack on climbs and thereby gap the competitors, knowing that only other climbing specialists will be able to stay with them, or simply to maintain a high pace that others cannot match. A successful escape can help the climber achieve a victory if the race has a mountain-top finish, or even in a flat finish if the climber is able to maintain his lead after the climb is over. Climbing stages, along with individual time trials, are key stages in winning long stage races.
