"""Marathon Man"" For Jerry Dunn of Spearfish, running has become an obsession. For example, on Oct. 3, 1998, Dunn began running a marathon a day in New York City’s Central Park. He ran his 29th marathon on Nov. 3rd, the same day as the 29th annual New York City Marathon. A few years back, Dunn ran 104 marathons, a record for a single year. To say that Dunn sets unique goals for himself would be an understatement of ""marathon"" proportions."
