Bouldering in Fontainebleau, last day of the trip so went straight into harder routes rather than warming up. Felt unhappy at the top of a route so decided to do a controlled jump off onto mats below. About 1.5 metres up. Two people spotting me and two mats out. As I landed my left ankle twisted badly. I had what turned out to be an open dislocation on my ankle (bone exiting leg and joint fully dislocated) requiring surgery and a long recovery - a year later and I'm still not at full capacity with what I was able to do.
