Last night in the chat room people were talking about casting distances. This prompted my interest in looking up the results of 'distance casting' events. So I did. Bear in mind that the following measurement are based on One Handed casting using special lines that conform to the contest rules but are not the normal lines you'd use on the stream/river.

I did not write down the names of the contests. I looked at the results of 7 contests. Some were indoor and some outdoor therefore, on average, wind did not play a role.

Here are the winning and 2nd place lengths, in feet (rounded off), of casts in the men's 'A' Division:
99, 99, 98, 94, 98, 119, 98, 113, 108, 106, 80, 99, 92, 98, 97, 99, 100, 99, 90, 117, 109, 113, 102, 97, 96, 95, 99, 96, 96, 111, 115(dq'd -oob).
The average 1st or 2nd place casts works out to be 101 feet.
