Remember when slacklining was just a way to prove to the other kids in the park that you had leveled up from ultimate frisbee? Well, it has reached new heights. Canadian Mia Noblet just broke the women’s record for the world’s longest slackline crossing. The 500-meter-long line extends from Rectory Tower to Castleton Tower in Utah’s Castle Valley, and was the stage for the world record-breaker in 2015. The line is so long that, when the wind picks up, it blows 30 meters to the side. Not exactly something you want to experience when you are hovering 120 meters above the ground. Good job Mia, both for making the crossing and giving me hair-raising vertigo via computer screen.
