1. Legibly record official times of arrival and departure from checkpoints. Time is recorded when the lead dog’s nose crosses the official line.

Ideally, set your watch for 24- hour (military) time and record all times in that form. If you aren’t comfortable with 24-hour time, or if your watch doesn’t have that capability, then be certain to indicate a.m. or p.m. with the time and get the ham radio operator to convert it.

Important: All watches used for timing must be synchronized to the second, and recorded times must be accurate to the second. In one of the Iditarod races, the winner edged out the second place finisher by only one second!

On arrival and on departure, musher and timer must both initial musher’s time card and checkpoint time sheet.


2. For each team, count the number of dogs coming into the checkpoint, including dogs that are in the sled. Also, count the number of dogs in each team when they depart the checkpoint. All departing dogs should be in harness and traveling under their own power.


3. When a team first departs from a checkpoint, the departure time becomes official and cannot be changed. If the musher runs a short distance out on the trail, decides that the dogs are too tired, and returns to the checkpoint for a longer rest, then that extra rest counts as trail time, not as layover time. Inform Can-Am Central if and when a musher returns or departs for a second attempt, but do not record it as a new official departure time.


4. Actual arrival and departure times should always be recorded without adjustment. If a time penalty or credit is to be applied to a team, do not try to adjust a recorded arrival or departure time to reflect the penalty or credit. The Race Marshal will apply adjustments where appropriate.
