This week's video is a Climber's Crag special featuring the channel's co-host Josh Rundle and free-running legend, Toby Segar. In the video, the duo attempt to break the world record for the longest dyno ever. Standing at an intimidating 2.85 metres, the record was set by US climber, Skyler Weekes, at Sheffield's Cliffhanger Festival in 2010. 

Pushing the bar (or in this case, the jug!) to 2.96 metres, can the boys clinch a new world record? You'll have to watch below to find out. Enjoy!
