Any death is terrible, but it is perhaps a little more understandable if it is the result of an undetected heart condition rather than an accident itself. Professional cycling dying during races is thankfully rare (and when you watch the kamikaze descents from Alpine or Pyrenean cols or the chaos of a sprint finish, it is a miracle that there isn't more), but if even one can be prevented by medical screening, then it is something that the UCI need to pursue.
