The Caber Toss is one of the many Highland Games offered by Mad Max Adventures near Edinburgh, Scotland.
A long tapered pine pole or log is stood upright and hoisted by the competitor who balances it vertically holding the smaller end in his hands (see photo).
Then the competitor runs forward attempting to toss it in such a way that it turns end over end with the upper (larger) end striking the ground first.
The smaller end that was originally held by the athlete then hits the ground in the 12 o'clock position measured relative to the direction of the run. If successful, the athlete is said to have turned the caber.
Cabers vary greatly in length, weight, taper, and balance, all of which affect the degree of difficulty in making a successful toss. Competitors are judged on how closely their throws approximate the ideal 12 o'clock toss on an imaginary clock.
