Lucas Barron will make history on Sunday when he lines up on the Dakar 2019 start line in Peru, the first person with Down syndrome to take part in the grueling race. Barron, who has been training for a year and a half alongside his father, will ride aboard one of 500 vehicles tackling the historic rally first run between Paris and Dakar in 1979. The requirements were the same as for any other competitor: passing all the medical exams and supplying the necessary documentation.
