(The caber is not thrown, it is tossed, and it's not distance that matters, it's all about style. The "tosser" rests the caber against his shoulder and lifts it vertically off the ground. The objective is to toss the caber in such a way that it turns end over end in the air and lands with the lower end pointing towards the tosser in a relative twelve o'clock position.
According to the Guinness Book of World Records, the largest caber ever tossed was 25 feet long and weighed 280 pounds. I wonder what they call the guy who tossed that one.)
