Corrigan Sports Enterprises (CSE) announced that the 2007 CareFirst BlueCross BlueShield Half-Marathon at the Under Armour Baltimore Running Festival has sold out for the fourth-straight year. The announcement comes after organizers increased the number of participants from 4,500 to 5,500 this year. The waiting list for entry into the half-marathon is now greater than 300.

Overall registration is up 20 percent compared to this time last year. All the other races are close to selling out and, as a result, the event has passed the 12,000 runner mark for the first time in the seven years of the Running Festival.
