The 2014 UCI BMX World Championships Rotterdam have ended in heartbreak for defending champion Caroline Buchanan on a day that was marred by a series of high profile crashes. Having rode a fantastic Time Trial the day before to grab the silver medal, the defending champ was left battered and bruised after crashing during her last heat earlier in the day, and was 50-50 as to whether or not she would even be able to continue racing having already qualified for the quarter final.
