Last night I read Matt Fitzerald's post on meeting Haile Gebrsalasie and other Adidas athletes who were also gold medalists from the Osaka World Championships in 2008. Marathon world record holder Haile Gebrselassie was joined by Tyson Gay, Jeremy Wariner, Allyson Felix, Veronica Campbell-Brown, Christine Ohuruogu and Blanka Vlasic at the world renowned Athletes' Performance Institute (API) in Los Angeles where the athletes gave insights into their running styles and discussed how they plan to successfully defend their world titles this year.
It was a great post comparing Haile Gebrsalasie to another charismatic athlete, Mohammed Ali. You can read his post here. You can read Matt's interview with this outstanding runner here.
I also found this video of the event including Haile's 4 minute/mile pacing on a treadmill and the throwing of his arms in the air. That is quite a stride that he has! Reading Matt's post will help you appreciate the video.
