Competitor bio:

Arno is 38 years old and first took part in endurance sports in his late twenties. The World Marathon Challenge is his biggest challenge of all, however, his honeymoon trip around the world with wife Meriem! As a father and husband, and busy with work, his main challenge has been to find available hours to train for the event. This predicament has often led to nice sunrises during early morning training runs. Arno has always followed his belief to be the best version of oneself and to make the most out of every situation. He was born and raised in The Netherlands.
