Philadelphia’s annual half marathon takes place on Sunday but it will be a little different this year.

KYW’s Hadas Kuznits reports that, for starters, the name of the Philadelphia Distance Run has been changed. Starting this year, the 33-year-old race is being known as the ING Rock-n-Roll Philadelphia Half Marathon:

“The Rock n Roll series is a nationwide marathon and half marathon event group and it’s the first year that we’ve brought the Rock n Roll name to Philadelphia.”

That’s event manager Malain McCormick (right):

“The Rock n Roll marathon series was founded by a man who wanted to combine music with running so you have live bands every mile. There are also cheerleading squads on the course to pep up the runners and there’s also a big finish line festival.”

And for the first year ever, the half marathon is sold out with over 18,500 participants registered:

“It is a record for us, yes, for the Philly distance run transferring over to Rock n Roll. It’s a 33-year-old event and this is the highest it has been.”
