hahahahaha - and the first 4 of those times are from this year! You're joking right?
Malmo, I just don't undestand why you put 2:06-2:07 values on Mutai when the record was 2:05:52 already by Robert Cheroyiot. To be fair, its ok to assume Mutai is better than RK, so why would he be slower?
Also, look at the Boston course compared to London or Berlin. If they can take advantage of the downhills, the course should be faster than London and Berlin. The old idea of Boston being a slower course can now be discounted consider the top five times are:
Aid of wind or not, the course is not slow.
