He added wins at the Indiana DIII Championships and won the inaugural MIAA decathlon title. Spahr's success in the vault carried him to the national stage, where he qualified for the NCAA Championships in the heptathlon during the indoor season and the decathlon during the outdoor season. Matthew Schaefer earned All-MIAA status at the outdoor championships. On the women's side, Olivia Andrews set the indoor and outdoor program record as a freshman, becoming the first Trine woman to vault over 11 feet. She won the Indiana DIII Championships, the first for a Trine woman, and claimed the MIAA Outdoor Championship. Avery Boyce vaulted to #2 all-time at the MIAA Outdoor Championships to mark the first time Trine had two All-MIAA performers in the event.
