Running is a popular activity in Portland, and every year the city hosts the Portland Marathon as well as parts of the Hood to Coast Relay, the world's largest long-distance relay race (by number of participants). Portland serves as the center to an elite running group, the Nike Oregon Project, and is the residence of several elite runners including British 2012 Olympic 10,000m and 5,000m champion Mo Farah, American record holder at 10,000m Galen Rupp, and 2008 American Olympic bronze medalist at 10,000m Shalane Flanagan.
