Phone calls: We know you have friends and family who want to track your progress during the race.  Please ask them to do so via the website, which will be updated with results throughout the race if weather and conditions allow.  During the race, our phones are used to contact checkpoints and facilitate racer safety.  If a true emergency arises, and someone must contact a racer or race personnel, then this number may be used:                  In the history of the race, only five or six such situations have arisen.  Events such as death in the family or imminent birth of a child come to mind.  Arranging post-race transportation is NOT an emergency.

Please do not call any of the checkpoints, including the Point Mackenzie General Store.

 RACE TRAIL ETIQUETTE

Susitna 100 and Little Su 50K

Road & Trail Use
 Please yield the trail to motorized vehicles and all dog teams.
 For safety sake pull off the trail if you stop for repairs, change clothes, etc.

Runway Etiquette
 Do not bike, ski, walk, run, snowshoe, camp or sleep on any runway.
 Runways are usually defined by a groomed, maintained area, much longer than wider, and having "cut" tree boughs or other flagging placed along it's length (at both ends for sure). Pilots depend on these groomed runways to transport their food, family, friends and clients. Runways are of utmost concern to those using them, and are of a shouting if not gun toting offense when violated. Several are found on Flat Horn Lake and one at Luce's Lodge.

Restroom Etiquette

Restrooms at Point Mackenzie General Store are for restaurant patrons.  Racers please use port-a-potties.
 Always ask at a checkpoint or lodge where the designated restroom is!

 Do not defecate on race trail.
 Do not use pee bottles indoors at checkpoints.

Sleeping between Checkpoints (Susitna 100)
  If you are going to bivy (sleep) in between checkpoints please tell the checker that you intend to do so.
  If you bivy in between checkpoints please do so just off the main trail, but still in sight of the trail, so other racers and our snowmachine rovers can see you. This is very important! Attach your flashing light to your bike, ski pole, or sled to alert passing snowmachines to your presence.  Be sure it is turned on and flashing.
