This dissertation concludes that the symbiotic relationship between two competing cultural traditions of marathoning, Corrival and Pageant, simultaneous creates and eliminates barriers to marathoning participation. Using John Caughey's strategies for studying cultural traditions and Pierre Bourdieu's concept of capital to differentiate between and describe two different approaches to training for and participating in marathons among runners in the Baltimore-Washington Metropolitan Area (BWMA). Drawing on participant observation, interviews of runners in the BWMA, and an exploration of the geography of running in the BWMA, contextualized by discourse analysis of three prominent marathon training guides and the covers of the two most influential running magazines, this dissertation also explores the strategies individuals' use to overcome actual and potential obstacles to marathon participation, such as parenting or restrictive work schedules.
