The results did not list by Country, but I believe Israel ran 2:07.20, 2:07.33, 2:07.45 and 2:09.51.
Also An Italian Man broke Baldini's National Record by 3 Seconds by running 2:07.19
Swedens 8:05 Steepler Muhammed ran a National Record 2:10.04 to win the Over 40 Division by 40 Seconds
19 under 2:10, 30 under 2:11, and 33 Under 2:12
Maybe there is something to the shoes.
