Sunday was a day of firsts in Chattanooga. The city hosted its first-ever Ironman Chattanooga, with about 2,400 people taking on the 2.4-mile swim, 116-mile bike and 26.2-mile race throughout the city and Walker County in North Georgia.

There were a few minor issues -- notably tacks and oil placed by someone on the bike route causing a few flat tires -- but for the most part it was a successful debut for the city.

For the male and female professional athletes in Chattanooga competing for the honor of being the first Ironman Chattanooga champions, it was also a day of firsts.

Matt Hanson of Storm Lake, Iowa, and Canadian Angela Naeth each won the men's and women's races -- the first career Ironman victory for both athletes -- and they finished to thunderous cheers from thousands of spectators who lined the streets.
