Riders branch in organizing a 24-hour 1000 mile run with over 175 riders taking part. The previous world record was 152, however the UK riders were pipped to the post by another US ride of over 400 riders. Currently the association is headed by Michael J Kneebone. IBA Sanctioned Events The IBA suggests several types of long-distance rides to challenge riders. It is perhaps best known for the Iron Butt Rally, an organized event that is invitation only, through a raffle system. Additionally, the Iron Butt Association hosts the Saddle Sore 1000, the Bun Burner 1500, the Bun Burner Gold, the 50 cc Quest, the National Parks Tour Master Traveler Award, the coveted 10/10ths Challenge, the very exclusive 100K Club, and other longer themed rides taking place on different routes around the world.

Iron Butt Rally The Iron Butt Rally is a competitive motorcycle road rally held in the United States. It was first held in 1984, and beginning in 1991, now takes place in odd numbered years, usually in August. The rally lasts 11 days, and riders often travel over in that time. During the rally, entrants earn points by riding their motorcycles to various "bonus" locations in the U.S. and Canada. A bonus is a task or destination with a point value. To earn the points for a bonus, a rider must provide evidence by photographing an object or scene, purchasing a particular item, or by various other means specified by the organizers. The rally consists of one or more checkpoints, which may be located anywhere the United States, and one or more lists of bonuses with locations, times of availability (if limited), and varying point values. Each leg of the rally has its own bonus list, and only the bonuses for the leg currently being ridden are known to riders and can be earned. A bonus list typically contains far more bonuses than can be earned in the time allotted during a leg. This introduces a significant strategic element to the rally, since each rider must determine for him/herself which bonuses to attempt, and what route to use to reach them, while still reaching the next checkpoint before it closes.
