Jax Mariash was at the beginning of a quest to become the first woman in history to complete the 4 Deserts Grand Slam Plus. To achieve that dream she would need to complete five races longer than 250 kilometers across some of the most forbidding terrain on the planet that each took more than seven days to complete.
