Penn Relays Liveblog: Saturday

Today's the big day: Usain Bolt will take the track at Franklin Field as part of the US v. the World Events. And in case you can't be there, DP sports writers will be liveblogging it--and the rest of today's events. Also on the schedule are the 4xMile champs, hurdles, and the 100m dash.
