Though running up the east face of Boulder's first flatiron may seem unfathomable to most, one man has managed to do it in just 9 minutes and 23 seconds. This reportedly broke a previous record set in 2011.

Michael Reese, 26 of Boulder, made the climb up the First Flatiron without the use of technical rock climbing gear along a 5.6-rated route called "Direct Route." A fall on 1,000+ foot route could have been deadly. According to Mountain Project, the route Reese used to ascend the formation would typically consist of 10 pitches using a 50-meter rope.

Watch the video in Reese's Facebook post below to see him charge up the peak.

Free-solo climbing involves ascending technical terrain without the use of protective gear. It is extremely dangerous and can result in serious injury or death.

According to the Denver Post, the previous record was set in 2011 when Stefan Griebel climbed the route in 9 minutes and 25 seconds. Read their interview with Reese here to find out more about how he trained for the feat.
