I have a bicycle obstacle course which I take around to schools, and I'd like some more ideas for obstacles please: I have two limbo bars which the children have to pass under, a long plank with 'rungs' across it like a ladder that they ride along longitudinally, a see-saw, two planks at about a 30 degree angle to each other with a short gap in between them, and then I set out tightening curves with cones that they ride through. I also have a section in which they take a bean bag from the top of one cone, transfer it to the other hand and then throw it into one of three different hoops lying on the ground to score points. The children who use it are usually in the 12-15 year age group, and the idea is to sharpen their bicycle handling skills as well as having a bit of fun. Any ideas will be gratefully received. Thanks in anticipation.
