Exercise is a proven way to relieve stress and release endorphins. So it’s no coincidence that Washington, D.C. has recently held the title of both Most Stressed City in America and Fittest City in America (which it lost to Minneapolis last year). Still, running is a great way to escape traffic and de-stress. Explore the capital with these seven great running trails.
This is possibly the most iconic route in D.C. The loop connects the Lincoln and Capitol Building, covering four miles. You will pass the Washington Monument, Smithsonian museums and many, many tourists taking selfies. There is the added benefit of plenty of water fountains so you don’t need to carry a water bottle.
This four-mile loop is perfect for recovery running. It is relatively flat and paved, and cooler because it’s by the water. Along the course, enjoy watching planes take off and land across the river at Reagan National Airport.
Looking for the perfect route for a long run? Look no further. The Chesapeake & Ohio Canal offers 184 miles of open trail, taking you from Washington, D.C. to Cumberland, Maryland. Give your knees a break as you pass gravel, dirt, and even grassy patches. For you crazy ultra-runners who want to do it in one go, there are campsites and lockhouses along the path.
