As of 2003, the city has an estimated population of 170,164 and the density of 1,130.28 persons per km. The total area is 150.55 km. Takaoka is the second largest city in Toyama prefecture.
Although it was not the national record he had hoped for, it was third successive 2:07 marathon for Takaoka, having run 2:07:59 in the 2003 Fukuoka Marathon and 2:07:50 in the 2004 Chicago Marathon.
Because Takaoka requested a faster pace, two pace men - Abner Chibu of South Africa and Teodoro Vega of Mexico - were recruited to run the first 5Km in 14:40 followed by 3 minutes for each kilometre until 30Km, while the third pacemaker was going to run 15:05 for each 5Km.
At around 14Km Takaoka asked for the race pace to increase and it did pick up temporary from 3:05 for 13th and 14th Km to 2:58 for the 15th Km.
