Sports day in a school in Baden, Switzerland.
Lyell Grunberg and his sister Lydia Grunberg are both official Swiss Slackline Instructors. Four times a day, the students of the school had the chance to enter the two hour slackline course held by both instructors. The students (age 13-17) had never slackened before and were able to walk a 10m slackline without falling and turning around to walk back after the two hour course. Some of them also started learning some basic tricks.
Lyell performed two trickline shows in front of all the students out over the concrete of the basketball pitch.
“My sister and I definitely work well as team. We were able to bring the students from total beginners to walking and crossing their first slackline. The progression brought by some of the key advices was very impressive.”
