Some of you have asked for updates on required rest times remaining, so here's an update. In the table, you can see the rest times taken by each of the top teams in the first three checkpoints. If you deduct their start differential from their cumulative total rest, you get the remaining rest time. You can do your own analysis -- and speculation! -- about various strategies for early rest vs. late rest by each of the teams.
The eight top teams have all "hit their numbers" exactly on 30-minute increments. Matt appears to have "lost" 12 minutes by overstaying at Sourdough. Ed Hopkins appears to have overstayed 5 minutes in Meiers and understayed 6 minutes in Tolsona. I have no idea how that will be worked out by race officials, or if it will even matter. I'll update again when the teams have all left Mendeltna.
It's hard to explain how complicated time-keeping is for teams out on the trail. Everyone is exhausted, hungry and cold. I can tell you from first hand experience that it's very easy to lose track of the little things. It is a testament to ALL the teams that they get it right so much of the time... Go SPK!
