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. Lindgren also competed against Mills in the 1965 AAU Nationals meet, where they raced the . Mills won with a diving lean, while both were timed in 27:11.6, a new world record shared by Mills and Lindgren. The mark was also superior to the then world record for 10,000 m of 28:15 held by Ron Clarke. T&F News converted their mark to 28:10. But perhaps Lindgren's greatest race came during a May 1966 NCAA Regional meet at age 20, in the 3-mile run on a dirt track during a cold, windy day in Seattle. He raced to 12:53.0, just missing the world record of 12:52.4 held by Ron Clarke. Both times were superior to the then world record in the 5,000 m of 13:24. T&F News converted his time to 13:21. Collegiate and retirement Lindgren attended Washington State University in Pullman, Washington, where he majored in political science and minored in Russian language. While at Washington State, Lindgren won 11 NCAA Championships. (His only loss at an NCAA championship was to Jim Ryun in the 1968 indoor race.) He was one of only two people to ever defeat Steve Prefontaine in an NCAA Championship. (Lindgren won the 1969 NCAA Cross Country Championship in which 1968 NCAA champion Mike Ryan finished second and Prefontaine third.) He competed sporadically after graduating from college but without any notable success. Since 1980, Lindgren has lived in Honolulu, Hawaii. He continues to run regularly, active in the Hawaii running community. He coached the University of Hawaii's women's track and field team 2005–2007.
