The original Ultra Challenge® in its 10th year, with a varied 60% off-road. A Richmond start, along the Thames, then towards the North Downs and on through wonderful Surrey & Sussex countryside to Turners Hill at halfway (with optional camping). The Full 100 km challenge heads up & over the South Downs before the welcome sight of the Brighton coastline and an unforgettable racecourse finish line. A classic challenge – and one for your list!
