BALTIMORE (AP) - Runners get their chance to jog under Baltimore's harbor this weekend.
The Maryland Transportation Authority is sponsoring the 5K run Sunday through the Fort McHenry Tunnel.
The course takes runners through the tunnel and back again Sunday morning.
Transportation officials say the race will close the right northbound tunnel for several hours.
The race begins at 9 a.m. and is expected to end around noon.
Registration for the race costs $25 in advance and $30 on the day of the race.
Proceeds benefit the Special Olympics.
