The first person to cycle to the South Pole.
Leijerstam used a modified version of the commercially-available Sprint trike, made by recumbent tricycle manufacturer Inspired Cycle Engineering (ICE). She chose to go with a recumbent trike because it would allow her to maintain stability in the often very-high winds. This allowed her to concentrate simply on moving forward, instead of having to waste time and effort keeping her balance. The strategy paid off, as she not only made it, but also beat two other cyclists who had set out for the Pole on two-wheelers, days before her Dec. 17th start date.
