The sad reality is that most catastrophic failures in cross racing result from very simple factors. I have compiled a small list of race ending mechanical problems that could have been avoided with a small dose of precaution and a dash of extra care. These are not all or even the most common mechanical issues in cross racing but these all have two things in common: 1. They can absolutely end your race, giving you a regrettable DNF. 2. They can easily be prevented.
