TD Rule #4 FAQs
Rule 4 reads...
Advancing (forward) on the route by any means other than your own pedal power is strictly prohibited. No drafting. Use of any type of air scoop or umbrella sail intended to harness wind power is also prohibited. TD is a solo challenge, however, racing in the company of other racers is permitted provided all racers maintain separate gear. One complete survival kit per racer.
In the event of a serious mechanical or medical emergency that renders a bike unrideable, a rider may hitchhike by motor vehicle in ANY direction to repair the problem. The location of the incident must be well documented by SPOT tracking or other GPS logger. A rider may also receive assistance returning back to the exact location of the breakdown to begin forward progress. Again, the entire incident, from breakdown to return to the route must be fully documented by GPS.
 A challenger may ONLY accept motor vehicle assistance off/back to route from bystanders and passersby or, in the case a commercial transportation source is available. 'Bystander/passersby' refers to purely coincidental encounters. A racer may not accept a ride from a race spectator (a.k.a 'super fan') or contact friends and/or family (private parties) living along the route for direct assistance.
