And finally, in what may have been the most extraordinary athletic achievement of the weekend, Kelvin Kiptum of Kenya won the Chicago Marathon with a time of 2:00:37, breaking the previous world record of 2:01:09 by 34 seconds. That's right - he was the first person to run a sanctioned 26.2 mile race in under 121 minutes.
Which means, of course, that it is practically inevitable that at some point - probably sooner than later - someone will run a sanctioned marathon in under two hours.
In the women's race, Sifan Hassan of The Netherlands crossed the finish line first in 2:13:44, the second fastest time ever run by a woman; she beat the course record by a woman by 30 seconds.
