In skyrunning, a '''vertical kilometer''' is an uphill mountain running race with an elevation gain of 1,000 metres. The Vertical Kilometer World Circuit also defines it as covering less than 5 km.<ref name="Vertical Kilometer World Circuit 2017">{{cite web | title=Vertical Kilometer World Circuit launches | website=Vertical Kilometer World Circuit | date=2017-01-16 | url=https://vkworldcircuit.com/vertical-kilometer-world-circuit-launches/ | access-date=2022-05-23}}</ref> Trekking poles, which are allowed as optional accessories, are often used in vertical kilometer races.
