Nutrition partner information coming soon!

1We have a policy of zero tolerance for littering. We are determined to make this a “leave nothing but footprints” event. Any food or drinks you consume during the course segments must be done in place, and if you litter anywhere on the course you will be immediately disqualified and fined by authorities.

2Please make sure you slow down enough (on the bike in particular) to take on any nutrition needs you may have, and make sure you secure them well not to let them drop. At the aid stations there is a dropping zone for your litter that you must absolutely respect.

3On the run course you will not be allowed to consume any nutrition, solid or liquid, that carries trash with it, outside of the aid station zones. We recommend you carry a fuel backpack, especially if you are doing the full distance.

4We are sure you appreciate these measures as much as both we, and all residents, do, in order to keep the region clean and make sure it receives us with open arms for many years to come.
