10:21 am EDT:

Ruth Chepngetich (KEN) continues to lead the women's race but she is slowing. She is now on 2:09:38 pace. The World Record is 2:11:53, so she is still a couple of minutes ahead of pace. She is over 35km into the race.

10:05 am EDT:

Ruth Chepngetich (KEN) comes through 30km in 1:31:49. She has slowed a tad and is now on 2:09:09 pace, which is still World Record pace. She is about two minutes ahead of Kebede (ETH) in second. They are the only to have come through 30km thus far.

9:00 am EDT:

The lead men split 29:27 through 10,000m. There are ten men in the lead pack and they are on 2:04:20 pace. Zach Panning (USA) and CJ Albertson (USA) lead the chase pack alongside a number of Japanese runners. They split 30:01 through 10k.
