I wish we had this explained to us before the race and wish the racers also had a better explanation. Not sure if anything would have changed in the overall outcome but it would have made it a much more even playing field.
UPDATE: I apologize to Grant that wrote the very informative article explaining the Portugal race format and want to make clear that he does not direct or have anything to do with the event. He was present at the race this year and thought it would be very helpful to all of us to get a good explanation out there. Thanks Grant!
