Dennis Kimetto set the marathon 2 years ago and subsequently had a fairly strong 2015 London ( 2:05) followed by some drop outs and a mediocre London this past spring. He has only run 6 marathons and is only 32 but seems to be written off by a lot of people. I would like to see him get back to form and go head to head with Kipchoge in 2017. I guess we will find out when he runs Chicago where he is at.
