Shalane was never going to beat Jeptoo yesterday, but I was taken aback by her naiviete', reacting heavily to the crowd noise early (a killer in the marathon-you have to tune them out in the early stages, even if you have to wear earplugs!), and fighting off surges, etc.. Meb I think was in the same relative position at the outset, but made his effort in a more strategic, measured way Using the crowd in the final miles) and perhaps having a bit of luck with his competition seeming to have an off day.
Side note- my impression was that in the early stages there was at least a slight tailing wind, in which case, the athletes in the back of the front pack "V" formation were getting an assist while blocking the wind that could have helped Shalane, making her effort even more remarkable. Coupled with the stomach probs (hypnotremia? Nerves? both?), she could have definitely scared 2:19 with a more even effort.
Great effort, I hope she comes back, paces herself, and wins in 2:19.
PS Desi seemed to nail the effort perfectly for her comeback.
