so,...just your opinion. What do you think the best performance of 2007 was in sprints (up to 400m), mid distance (800 thru 2 miles) and 5k plus? It doesn't have to be world record to qualify, just the most impressive performance either male or female.
Mine...
A. Felix 200 meter at WC
A. Webb Mile AR
Geb's World marathon record
These are the ones I paid closest attention to. Yours???
