Registration for the 2012 Broad Street Run sold-out in five hours, compared to four days last year. Jeremy Jordan, director of the Sport Industry Research Center at Temple, says the race course's longevity, downhill slope, and enthusiasm of participants all play a role in its popularity. "The timing allows for participants to set a spring goal for running that significant, yet manageable 10 miles," Jordan said. "It's a nice way to come out of the winter." SIRC has researched participant satisfaction in the race.
