When you consider that in the early 1900s times for men were 3 hours 30 minutes(ish).......record is now approx 2 hours 2 minutes.
OK distances were not accurate early on but the improvement is staggering.
Today in the London heat the time was approx 2 hours 5 mins.
At my best I could only average 8 1/2 minute miles for half marathons. These guys are running 26 miles at speeds I could never achieve for even one mile (4 1/2 minute miles).
I just wonder what speeds will eventually be achieved........as I say, its mind blowing.
