It will be interesting to see how it plays out in reality as 61:45 and 62:15 is only a difference about 3 seconds per mile so you'd think for a while it would be one group. Does it stay that way or to avoid the awkwardness does group 1 start too fast or does Mo's group start slower on purpose and warm it's way up?
1) Mo Farah, Ibrahim Jeilan and Stephen Kiprotich will be pace group 2. Everyone else pace group 1.
2) Women will go through in 69.15-69.30 and negative split.
