Iron Butt Association
The Iron Butt Association (IBA) is a US-based organization dedicated to endurance motorcycle riding with a claim of over 60,000 members world-wide.
To earn membership, candidates should complete one of the endurance rides in compliance with the association’s rules, the easiest being the SaddleSore 1000 (1,000 miles/1610 km in 24 hours) or the Bun Burner 1500 (1,500 miles/2414 km in 36 hours).
There is also the Bun Burner Gold (1,500 miles/ 2 414 km in 24 hours), the 50cc Quest (Cross Country (from ocean to ocean) in 50 hours or less), the National Parks Tour Master Traveler Award (visit 50 parks in at least 25 states), the coveted 10/10ths Challenge (10 consecutive 1,000 mile/ 1610 km days) and the 100K Club (100,000 miles/ 160 935 km or more in one year), which is almost impossible to get into.
Upon completing one of these rides the competitor receives a certificate confirming he or she is now the member of the Association. The rider is also assigned a personal number and given a license plate back with IBA signage.
The IBA also hosts several rides, the most notable being the 11-day, 11,000+ mile / 17 700+ km Iron Butt Rally which is held annually.
