Most Boston runners pos split the course. It's not the weather. It's a big race and people don't know how to be patient in the opening miles (except the elite women who always start out jogging). The rest of the field doesn't know how to be patient and they start racing from the gun. They hit the opening downhill hard and pay for it later. Most don't know how to handle the hills leading up to Boston College. Check prior results. I'm guessing 80-90% of runners positive split the course significantly. And then they blame it on the weather afterward.
I'd wouldn't be surprised if you found this 80-90% positive split (if it is accurate) in every marathon.
