Boston Common: Boston Common is the country’s oldest public park, and has served as everything from a military camp to a cow pasture to a meeting spot for protest marches. Nowadays, runners, joggers, and strollers frequent the area, enjoying the many tree-lined trails. Even during the cold New England winters, joggers can be spotted, while some prefer to get their exercise by ice-skating on the frozen-over Frog Pond. Visitors who want to be only one block from Boston Common may opt stay at The Ritz-Carlton Boston Common.
Freedom Trail: For those looking for more leisurely activity, peppered with some culture, the Freedom Trail walk is a great option. A two-and-a-half-mile trail beginning in Boston Common and ending at the Bunker Hill Monument, it links sixteen historic Boston sites, including Faneuil Hall and Paul Revere’s house. History buffs looking forward to the trail will likely enjoy the Omni Parker House, known for its ghost lore and old-world grandeur.
Franklin Park: Part of the Emerald Necklace, a chain of parks in Boston and Brookline, Franklin Park is the largest park in Boston and features one of the oldest golf courses in the country, as well as baseball fields, tennis courts, and basketball courts. A famous spot for cross country races, the park is also famous for its former resident, Ralph Waldo Emerson, who lived in a cabin atop Schoolmaster Hill. Franklin Park is a bit of a hike from central Boston, but visitors staying at The Colonnade Hotel are only a short drive away.
Millennium Park: Opened just seven years ago, Millennium Park is a modern, high-tech spot. At 24.5 acres, there's plenty of space to run around in, and the BP Pedestrian Bridge is an architecturally-stunning spot for a run or walk. The park also has an ice-skating rink and an indoor cycle center, as well as beautiful gardens for your cool-down stroll. Stay at the Fairmont Chicago if you want views of the park like the one above.
Lakefront Trail: An 18-mile trail along Lake Michigan, the Lakefront Trail was built to promote commuting by bicycle. Located in Chicago's largest urban park, Lincoln Park, the trail is often packed with cyclists and joggers. Those hoping to run part or the entire trail may consider staying at the nearby Villa D' Citta.
Jackson Park: Known as the site of the "White City" in the 1893 World Columbian Exposition, Jackson Park was designed by the masterminds behind Central Park and Prospect Park. Part of the Lakefront Trail runs through Jackson Park and the park also boasts two walking and running trails, bird-watching trails, and basketball courts. The Chicago South Loop Hotel is a short drive away.
Capital Crescent Trail: The 10-mile Capital Crescent Trail runs from Georgetown to Bethesda, Maryland along the Potomac River. It’s one of the best maintained trails in the city and has beautiful views as it winds along the Potomac, through wooded parks, and on the sidewalks of upscale neighborhoods on the edge of the capital. Pick up running or biking from the southern trailhead under the Francis Scott Key Bridge in Georgetown or start at any point along the trail. The Ritz-Carlton Georgetown is near the end of the trail, so you can crash after your long workout.
C & O National Park: The C&O Canal, which operated from 1831 to 1924, runs through the National Park from Georgetown to western Maryland. Nowadays, hikers and bikers enjoy the old canal towpath for its views of the Potomac River Valley and a small section of the towpath is part of the Appalachian Trail. If you're in the mood to be right on the water, canoes are available for rent. The Four Seasons Washington D.C. is just steps from the park.
Rock Creek Park: Rock Creek Park offers more rugged trails for those who enjoy hiking—or very intense runs. There are also some paved paths for bikers, as well as dirt paths for equestrians. The Omni Shoreham Hotel sits at one end of the park.
