Do not impede traffic. If someone is nipping at your heels and you can't shake them off your back tire, don't be that person who doesn't move over. Move to the right as to make it easier for them to pass.

In the event of a mechanical or if you need to stop, move off to the side of the trail.

Dress for the weather and be prepared for unexpected changes (rain, wind, and cold).

Carry the proper food and water to keep your body fueled

Ride hard, push yourself, and make it a race to remember.

Bring the strongest bug spray you can find. Cloud of gnats so thick they cast a shadow. Windward side riding is fine but the leeward (east) was intolerable.
