5. Shipping/receiving supplies (to the course): In the name of equal opportunity for international riders, and to minimize the TD 'footprint', challengers are encouraged to race as reliant as possible on commercial services along the route. However, in advance of a start, a competitor may cache food or equipment resupply at US Post Offices only, care of general delivery. Typical practice is to ship a replacement chain and fresh bike shorts to the halfway point on route. If a racer misses a resupply due to PO closure, that box may be forwarded to another PO, and only a PO, down route.
5a. Once the race clock begins, a rider may be assisted by a third party in receiving emergency repair/replacement items only. Food resupply is not considered an emergency. No cookies from mom! Emergency items must be shipped using a commercial shipper such as USPS, UPS, Fed-Ex, DHL, etc. Items may not be delivered privately by family, friends or even anonymous persons. Items may only be shipped to a commercial address (P.O., motel, bike shop, restaurant etc.), provided that address is equally available to all racers. Use of a private address (residence) along the route is forbidden. Use of the Race Updates blog to 'broadcast' for help (ie. conjure 'trail magic') is also forbidden. Item 5 FAQs

The rules are simple and brief - ultimately, they depend on each rider's integrity, which means respecting and adhering to them whatever your opinion. If you can't police your own actions and abide by the rules 100%, please don’t ride and belittle the efforts of the honourable riders who can. Breaking or bending these simple rules is unfair to the other riders who are out there suffering just as bad as you are, yet are still playing by the rules.
