I saw some of the race yesterday, the leading woman (NZL) for most of the race seemed to run similar to Paula Radcliff. She started to stumble or lose her concentration around 18 miles or so and not sure where she finished in the end.
The men were cracking on at a fantastic pace, slotting in 4.35's or so for many miles. It's a shame that because it's mostly downhill that it won't count as a WR time.
