In the 1964 Summer Olympics in Tokyo, he finished ninth in the 10,000 m behind gold medalist Billy Mills after having sprained an ankle during training. Four years later, Lindgren tried to make the 1968 Olympic team but finished 5th in the 10,000 m and 4th in the 5,000 m in the Olympic Trials at Echo Summit, just missing the team at both distances. In his training just after college, he was said to have averaged 240 miles per week for one year, including allegedly running a 380-mile week.
