The dogs run at about 9 miles an hour. On average, we cover just over 100 miles in each 24 hour period. (Remember that we run during both the day and the night.) To measure this for yourself, look at the GPS tracker for a couple days during the race. Look to see what mile your favorite musher is at, and what time it is on the clock where you live. Tomorrow, at the same time, check the tracker again and see what race mile your favorite musher is at now. Subtract the smaller number from the larger number to see how many miles your musher has traveled in 24 hours. The number you come up with should be something around or over 100. If it’s not, the musher may have taken a significantly large rest during this time period. Check the numbers again tomorrow.
