What is the official size arena for western riding avents?

Question

Particularly for barrel racing, what is the official size arena for this?

Answer 1

It depends on what organization you are talking about for official, but average is 130 ft. wide by 200 ft. long. If you stick to average, it usually fits most organizations.

It's really more about barrel spacing than arena size. From the score line (starting line) to the 1st and 2nd barrels is 60 feet. The distance between the first and second barrels is 90 feet, and the distance from the 1st and 2nd barrels to the 3rd barrel is 105 feet.
