The CareFirst BlueCross BlueShield Frederick Marathon Weekend kicks off its fifth year this weekend. All festivities take place at Harry Grove Stadium, the home of the Frederick Keys.

The event starts at 11:00 a.m. Saturday, May 5th with the Health and Fitness Expo featuring vendor booths and demonstrations for not only runners, but for everyone. At 7:00 p.m., the Twilight 5K begins as runners weave their way around Mt. Olivet Cemetery. After the race, local band Poor Mary will entertain the crowd before the fireworks light up the sky at roughly 8:45 p.m.

On Sunday, the day begins with a sunrise service at 6:30 a.m. Following the service, runners from across the U.S. and several countries take to the starting line at 7:30 a.m. for the start of the CareFirst BlueCross BlueShield Marathon, the half-marathon, and the four-person team relay. Fans can take part in the Celebration Village and listen to live music from bands such as The Boa while waiting for the runners to finish. Registration has already passed last year's totals with more than 3,000 runners signed up thus far. The team relay and 5K are both nearly sold out, with more than 1,300 people registered for the half-marathon. Among the highlights for this year's event: Michael Wardian's attempt to break the world record for "Fastest Marathon While Pushing a Stroller," Dane Rauschenburg taking part in the Ferris Baker Watts, Inc. Charity Chaser program, where he tries to pass as many runners as possible to raise money for the United Way, and a possible surprise marriage proposal.
