"A variety of double, triple, quadruple, quintuple, and deca (10x) full distance events are also held each year. In a deca full distance event, for example, a 38 km swim is followed by an 1800 km bike race and a 422 km run. Astrid Benöhr holds the women's world records over the triple, quadruple and quintuple full distances.
In 1998, a double deca triathlon (20x full distance) was held in Monterrey, Mexico. The winner, Vidmantas Urbonas of Lithuania, completed the race in 437 hrs 21 min 40 sec."
