Istres Half Marathon
Istres Half Marathon is a rolling half marathon in Istres, France, held each November. A single circuit from the Étang de l'Olivier through the town centre, out past the Lavalduc and Citis ponds to the Étang de Berre shore, then back for a lap of the Olivier pond. Gentle but constant ups and downs. Late November in Provence is usually cool and dry, with temperatures of 6 to 14°C and a risk of mistral wind. The rises around Istres are small but relentless — train on similar terrain and race by effort, not pace.
