Brest Open Groupe Vert Tournament In French Indoor Swing In September and October, France shines with a trio of world-class indoor events. It kicks off in Orleans and moves to Mouilleron-le-Captif, before concluding in Brest. The Brest Open Groupe Vert is going strong for five years, with home grown champion Corentin Moutet in 2017 and emerging Polish star Hubert Hurkacz in 2018. Similar to Orleans and Mouilleron, the entertainment value in Brest is top notch, with a state-of-the-art arena and elite fan experience. Roger Federer won his lone Challenger title here in 1999.
