Hobby sports: These trends on Instagram and Tiktok you should know

In the past, there were fun runs and city marathons, training guides in book form, or sports clubs with volunteer trainers. Today, social media dominates among many recreational athletes as a source of information and inspiration. Here's an ABC of trends that are taking hold through social media and are worth at least a brief thought before you think that's something for you. #backyardultra Gary Cantrell, better known in the running community as Lazarus Lake, was probably not satisfied in 2011 that he had already come up with the probably spookiest running event in the world with the Barkley Marathons.

He also started the Backyard Ultras, which have now taken hold in Germany. The concept is simple: every hour, a round of 6.7 kilometers is run. The last runner or runner who runs a round alone wins. The record is 108 rounds. That sounds fun. Nevertheless, don't sign up on a whim. Even if twelve rounds don't sound like much at first: that's 80.472 kilometers. After just six rounds, you're close to the marathon distance.
