This bit isn't really rule-governed. It's impossible to cover off every type of sticky end or incident on the Mongol Derby. You won't know how you will feel until you're in the situation, and we won't know what resources are available to accommodate you until the race is underway. So, the following is a guideline, not a rule:
If we can get you back on a horse and back in the race, and you want to ride on, you are welcome to do so. Chances are time will have passed and the back up crews may have been moved forward on the course to stay in touch with the leaders in the field. In this case, you may have to be transported forward to re-join the main pack. This being the case, you will not achieve an official placing- you must ride every leg to officially 'finish'. If we transport you less than 1 urtuu you can take a 3 hour penalty and we'll call it quits.
