Official Title: Etude Des Troubles métaboliques Induits Par Une Course à Pied très Longue Distance, " La Diagonale Des Fous " de La Réunion / Metabolic Disorders in Ultramarathon Runners
Brief Summary: Acute consequences of ultramarathon running are still unknown as very little research has been done on the matter. The investigators will assess the consequences on the metabolism of runners in the ultramarathon Madmen's Diagonal on Reunion Island. Data from the literature suggest that runners undergo loss of zinc, copper, iron, magnesium not unlike the loss of metabolites in systemic inflammatory response syndrome. The purpose of this study is to assess the metabolic disorders (selenium, zinc, vitamins B9 and B12) in ultramarathon runners, during and up to 28 days after the Madmen's Diagonal which takes place on Reunion Island every year in October.
