What's the lineup for the Prefontaine Classic 2008? That's what I've been wondering too for the past couple of months. Finally, a couple of weeks ago, I decided to send an email to the organizers. I went to the main site - Prefontaine Classic and shot off an email to the id listed on that page. A week later I did get a response, telling me that they will be announcing the lineup this week. It also confirmed that Kenenisa Bekele will be running. If you look at their main page, it says Bekele as well as Meserat Defar will be attempting to break the men's and women's 5000 meter world record respectively. That's going to be something.
I was fortunate to get to go to the 2007 meet. Check out some pics here.
