Galen Rupp wins!

bibs: #1 Abel Kirui, #5 Sisay Lemma, # 10 Galen Rupp

Notes:
1.)  1st half: 1:06:10, 2nd half: 1:03:10
2.)  10 km from 20 mile marker for leader: 29:11 (!!)
3.)  position of 40 km marker was not on correct position!
– GPS analysis: 39 km – 40 km:  1087 m,  40 km – 41 km: 918 m
(typical error of analysis: +- 5 m)
– then 40 km split was 2:02:52
and 39 km – 40 km: 2:51; 40 km – 41 km: 2:52
– this analysis is in full accord then with the constant mile splits
4.)  slowest km-split was first km in 3:13
5.)  fastest km-split was 2:46 (39 km), 41 km has to be checked (see 3.)
6.)  up to 11 km Mary Keitany was faster in London than men in Chicago (!!)
7.)  fastest mile-split was 4:30 (24 mile)
