London: 5 best May values

On the buildings along the Schuylkill River, vibrant murals welcome visitors into Philadelphia. They've been peeking out from underneath bridges and along cement walls since 1984, when the city established the Philadelphia Anti-Graffiti Network, to redirect graffiti artists' energies toward enhancing their community. Over time, the nation's largest mural effort, the City of Philadelphia Mural Arts Program, sprung up. Now, in collaboration with local photographer Jacques-Jean "JJ" Tiziou, the mural has been elevated to an all-new level—seven-stories high. At Philly's airport, a nearly 50,000-square-foot piece will cover one side of the parking garage stretching from Terminal A to Terminal F, with roughly 18 images of community dancers narrowed down from thousands. The City of Brotherly Love has a history of dance, and JJ Tiziou has been right alongside the movement to document it. The project will employ 35 artists and take 18 months to complete before its final dedication in June 2011. The energy of the design, entitled How Philly Moves, will be palpable at 60 MPH while driving past it on Interstate 95, and it will be clear why Philadelphia could as easily earn a new nickname—the City of Murals. 25 Reasons We Love Philly Tickets Now on Sale for Philly's Cleopatra Exhibit More Top Travel Blogs

Bay to Breakers Marathon The annual Bay to Breakers 12K race* is a quintessential "only in San Francisco" experience. More mobile party than sporting event, the marathon draws more than 50,000 participants (some runners, mostly walkers) who start at the Embarcadero and head through Golden Gate Park out to the beach. Costumes are a must and range from Elvis impersonators to superheroes to Star Wars storm troopers—and some people wear nothing at all (don't say we didn't warn you!) Last year more than 100,000 people showed up to watch the show. While corporate sponsor ING has more recently tried to put an end to the public drinking—no more kegs on wheels—revelry is guaranteed. Top places to watch include Alamo Square, the front of the Conservatory of Flowers in Golden Gate Park, and the Finish Line on the Great Highway on the beach. May 16, 8 a.m.-11 a.m, *Whoops, we originally said "marathon."

This month's debut of the Hollywood epic "Robin Hood"—starring Russell Crowe and Cate Blanchett—has spawned a bunch of Robin Hood-themed events in England. While we don't know if Robin Hood truly existed or was merely a creation of medieval poets, we're certain that Sherwood Forest (where he supposedly lived) is one of the oldest and most majestic forests in Britain. It covers 450 acres of protected beech and birch woodland dotted with more than 1,000 magnificent oaks, most of which are over 500 years old. There are exhibitions devoted to the history of Robin Hood at the Sherwood Forest visitors' center, which is just outside of the village of Edwinstowe. Also worth a visit is Nottingham Castle in the city of Nottingham itself. A one-off exhibition by Sonja Klaus, the set designer for the movie, showcases the film's props, weaponry and costumes worn by Crowe (Robin) and Blanchett (Marian). And medieval jousts and archery competitions will be taking place in the castle grounds throughout May. Other Nottingham attractions include the Galleries of Justice history museum, Byron's former home of Newstead Abbey and the Caves of Nottingham Museum—showcasing caverns under the city which have been used as dwelling places since Saxon times. The highlight of the area remains the forest, though, which is magical to walk through. The largest tree is the Major Oak, which was a big even in the Middle Ages when Robin Hood was supposedly firing his arrows. Today it is more than 800 years old and weighs more than 23 tons. You can easily imagine Robin Hood hanging out behind the trees, after having poached the king's deer and robbed from the rich to give to the poor. National Rail from London to Nottingham with East Midlands trains take 1 hour 45 minutes. The Sherwood Arrow bus service 33 between Nottingham and Worksop calls at Edwinstowe.

The recent London Marathon has inspired Londoners with an urge to shed their winter beer bellies and work on their six-pack abs. You see lycra-clad joggers everywhere. New arrivals looking to keep up the fitness regime during their stay will find that London's a great place for urban running. Here's the best of three routes. The Thames Path, location: central London to the eastern and western suburbs This pedestrian path fringes both banks of the river Thames for 180 miles, cutting through the heart of London and offering the chance to enjoy one of Europe's most scenic jogs. Runs vary from stretches along one bank to loops taking in both banks and two bridges. To take in the most famous sights as you run begin at Tower Bridge (subway: Tower Hill) and jog to Westminster Bridge finishing up at the Houses of Parliament (subway: Westminster), a run of five-and-a-half miles. The Hampstead Loop, location: north London You never leave the city on this hilly run, yet with the muddy footpaths, extensive stretches woodland and welly boots and Labradors you'd be forgiven for thinking you were in the heart of rural England. The run begins at urban Kentish town subway or prettier Hampstead. From either location it climbs up onto Hampstead Heath, a huge hilly park covered in woodland and offering sweeping views out over London. Either option gives a run of four to five miles. Hyde Park and Kensington Gardens, location: Central London Central London's biggest green space is criss-crossed with running tracks. The longest is the outer circuit, a long oblong loop taking in the entire park and adjacent Kensington Gardens and passing Kensington Palace and the Princess Diana Memorial. The total distance is four-and-a-quarter miles and the park can be reached via the following subway stations: Hyde Park Corner, Marble Arch, Lancaster Gate, Notting Hill or Bayswater. Richmond Park location: south London In the far south of the city is one of the largest urban green spaces in Europe, so much so that it is home to herds of wild deer. Hampstead Heath in the north has wonderful views out across the city, whilst Battersea Park a mile south of Victoria rail station across the Thames is the only large park in Central London which abuts onto the river.
