Dina Mishev climbed 34,546 feet in 24 hours, a new world record. Using climbing skins, she repeatedly trekked up a 1502-foot trail, checking in with officials at the top off the trail, before skiing down and checking in with officials at the bottom. She did this 23 times in 24 hours. The record was set on February 8, 2009 during the 24 Hour Sunlight Challenge at the Sunlight Mountain Resort in Glenwood Springs, Colorado. tag:RecordSetterBook01

Using deft moves and kangaroo-like jumping ability, Rob Birdsong sets a new universal record with 11 tent circulations in one minute. Each circulation consisted of Rob entering the tent from one side door, exiting through the other side door, and then jumping over the tent back to his starting position. The record was set on December 14, 2008 at Birdsong’s apartment in Brooklyn, New York. Ryan Brown and Schuyler Van Horn witnessed and documented the feat.
