Richtman, Kaneland's Bradley-bound distance standout, won the 3,200-meter run and took second in the 1,600. Knights' throwing star Clayton Hannula did his part, sweeping the discus and shot put.
Their teammates did the rest, leading Kaneland to the team championship of the Northern Illinois Big 12 Conference meet.
Kaneland scored 143.50 points, with Yorkville (112) second. Kaneland, also conference indoor champ, last won a share of the conference outdoor title in 2015.
It's exactly the way Richtman wanted to go out.
"It's a good night for us," Richtman said. "It's definitely very exciting to come out with the team championship. It's one of those things that you always look to."
Richtman engaged in one last memorable 3,200 duel with Sterling's Jacob Gebhardt. The two friendly rivals since the eighth grade were neck-and-neck through seven laps.
Gebhardt, an Indiana recruit, surged ahead to start the bell lap.
But it was Richtman who had the final burst in the final 200, winning in 9:28.10 to Gebhardt's 9:31.45.
"I love racing against these guys," Richtman said. "It was a really fun race, being that close together. I needed a lot of mental toughness to stay in there. It's definitely a high point of my season so far."
