As someone with a 5:38 delta, I'm very anxiously waiting for BAA to announce the official cutoff.

In the meantime, if you're at all curious about the kinds of levels to which people go with trying to predict the cutoff check out this blog[1]. This is from Brian Rock [2], who every year collects data about a lot of marathons all over the world and then tries to guess the official cutoff for the Boston marathon. Very cool stuff!

Brian Rock's tracker is great. It's a ton of work to collect and maintain that estimate throughout the year, so we hope he keeps it up!
