Indian mountaineer Malli Mastan Babu also had the eminence of setting a Guinness world record by surmounting the Seven Summits in 172 days in 2006. The world record for completion of the Messner and Bass list was 136 days, by Danish climber Henrik Kristiansen in 2008. Kristiansen completed the summits in the following order: Vinson on Jan 21, Aconcagua on Feb 6, Kosciuszko on Feb 13, Kilimanjaro on Mar 1, Carstensz Pyramid on Mar 14, Elbrus on May 8, Everest on May 25, spending just 22 days on the mountain (normally, expeditions take up to two months acclimatizing, laying ropes, etc.) and finally Denali on June 5, beating Ian McKeever's previous record by 20 days. Vern Tejas set the new record for the same, in 134 days. Tejas began with summiting Vinson on 18 January 2010 and ended with summiting Denali on May 31. This was Tejas' ninth time to complete the Bass Seven Summits.
