I’ve seen a few chaps free running over walls, railings and benches along the promenade quite a few times. Last week a couple of them were using camcorders to capture their jumps over and on to walls in Meols Parade Gardens.
Free running is also known as parkour and you can read more about it on wikipedia.
I’ve had a very quick search on youtube and while I’ve not found anything published recently, this video (with music soundtrack) from 2009 demonstrates what’s involved. Since that video has been shot the sand banked-up against the wall has gone. It was removed as part of the exercise to stop wind-blown sand blocking the road – as captured here.
