 The RacingThePlanet Ultramarathon was introduced in 2008 as the 4 Deserts saw a desire for multi-day, multi-stage races in new countries.The concept was to supplement with 4 Deserts Race Series with one-off races in new locations each year.These locations did not have to be deserts, but it was preferred that they would retain some of the most desirable elements of the races in the original series including locations that were off the beaten track and where beautiful, cultural and physically challenging courses could be set.
