I ran my first marathon here in 2010. I also ran my first half marathon in 2009 which is really difficult because of the hills. I think it was easier when I ran the marathon the following year as I thought it was flatter. It can get congested somewhere when half/full runners merge towards the last miles. The expo is great! The shirt is awesome! The race happens on Saturdays if that is your preference! Highly recommend the Baltimore Marathon!
