The Cooper test is a test of physical fitness. It was designed by Kenneth H. Cooper in 1968 for US military use. The point of the test is to run as far as possible within 12 minutes. Hence, in contrast to other runs, the Cooper test fixes the time instead of the distance.
Jakob and Anton Schoser took part in a 12-minute Cooper run on 15 September 2012. They are both members of the Brussels Finnish Athletics Club 'Flying Finns' which regularly organises Cooper runs. Jakob ran a distance of 2525m while his younger brother Anton covered 2270m. In the case of Jakob, this was not even his best performance as he had managed to run 2610m one year earlier.
