What's going on?

  Jeff King is a musher who is racing this year. He is originally from Denali, Alaska. Currently he is 58 years old. Right now he has all of his dogs and is in 10th place. He checked into finger Lake at 6:15 and left at 6:16 today. He was going 7.79 mph. at this rate, the reward at the finish line will be given to someone else. WHO WILL WIN?
\(P.S. He's old enough to be my grandfather)
