“I did it and I finished.” The Frappadingue slogan sums up this race which has become legendary in only 5 years of existence. On paper, the concept is not particularly terrifying: 12 kilometres, a couple of obstacles and that’s it. In reality, it’s quite another story. The Montreuil-sur-Mer Opale X’Trem is a combination of unpredictable, adrenalin and commando-style physical challenges. Scale an army of straw bales, climb with a cord, flounder in troubled waters, and find yourself suspended in a void. Even so, every year 5,500 people slip on their race bibs for their love of risk.
