The most exciting 10k to come online in years! Don’t miss out on the chance to run or walk over the Chesapeake Bay.

A beloved Maryland tradition is back in a new, exciting format! This 10 kilometer, 6.2 mile point-to-point course will take runners over the eastbound span of the 4.35 mile long Chesapeake Bay Bridge, which reaches 186 feet at its tallest point. Runners will experience water vistas dotted with sailboats and cargo ships from atop a major dual-span bridge that doesn’t allow pedestrian traffic at any other time of the year. This event happens once a year and is the only way to cross this majestic span on foot.

The race is open to participants of various levels of fitness and physical abilities as long as you are able to complete the event in under 2.5 hours

After departing the start line near Northrop Grumman bayside campus, participants travel about a half mile over MDTA property before they leave the western shore and begin ascending the eastbound span of the Chesapeake Bay Bridge. There is a gradual but sustained climb for approximately 1.7 miles until you reach the midpoint of the bridge and the first water station. During those first two miles, runners will climb to nearly 200 feet above sea level. The climb isn’t overly steep and has a maximum grade of only 3%. You will be almost 200 feet above the bay – so don’t forget to check out the view!

Fortunately, what goes up must come down. After passing through the water station, runners descend the same 200 feet over the course of 2 miles before reaching the eastern shore and our legendary finisher’s celebration.
