What I'm doing: It's likely that my wife and I will go hiking on our own on one of the weekend days. I might also go and take in the Suntrust National Marathon.
What else I recommend: The Kelly race is a big Baltimore tradition. There are also other St. Patrick's Day events around the state, along with the pub run (which is being set up by a group that I run with sometimes -- all links are after the jump).
Other options:
Weekday options - ESRC weekday runs, Rockville All-Comers Group Fun Runs, Glen Burnie daily walking programs, Open track workouts Fleet Feet Sports, Gaithersburg Fun Run/Walk, Monday runs at Federal Hill
Saturday - NCR Trail Snails Saturday training runs, McDaniel College 5K Track Run, St. Patrick's pub run, Frederick Running Festival 10 Mile Training Run, Denton St. Patrick's Day 5K Race / Fun Walk
Sunday - KELLY St. Patrick's Day Shamrock 5K, Shamrock 5K, BRRC Group runs at Goucher, ESRC Salisbury-area Sunday runs, HCS Operation Iceberg race #6, Lower Potomac River Marathon, RASAC Susquhanna 5K
