History
The conference was formed in 1971 by independents Caston, Culver, Northfield, and Triton, and former Mid-Indiana Conference (MIC) member North Miami. The conference grew in 1976, as Manchester joined from the Northern Lakes Conference (NLC), Southwood joined from the Mid-Indiana Conference, and two recent consolidations, Whitko (1971) and Tippecanoe Valley (1974) joined. Culver left for the Northern State Conference (NSC) at the same time. This incarnation would last for two years, until Caston left for the Midwest Athletic Conference.
Triton left for the NSC in 1980, and was replaced by two MIC schools: Eastern (Greentown) and Oak Hill. Eastern rejoined the MIC in 1987, and was replaced by NLC school Rochester. The lineup changed once more in 2006, when Oak Hill traded places with Central Indiana Athletic Conference member Wabash. The latest change was in 2015, as Maconaquah and Peru joined from the folding MIC.
Rochester and Tippecanoe Valley share a traveling trophy that is called the bell.
In 2023, Tippecanoe Valley announced they would be exiting the conference to form their own 6 team conference featuring John Glenn, LaVille, Jimtown, Knox, and Bremen. Tippecanoe Valley was independent for the 2023-24 school year before joining the new conference.
Also in 2023, the Hoosier Conference announced that Lewis Cass would be leaving the conference at the end of the 2022-23 school year to join the TRC.
On June 1, 2023, North Miami announced they would be exiting the TRC to join the Hoosier North starting at the beginning of the 2024-25 school year. On the next day of June 2, Northwestern announced they would take North Miami's place in the TRC, exiting the Hoosier Conference.

Rivalries
Non Conference
- Lewis Cass vs Caston, Logansport and Pioneer
These schools share a Cass County rivalry in multiple sports.
- Maconaquah, Peru vs North Miami
The three schools battle for Miami County bragging rights. From 2015-2024, all three schools played in the TRC.
- Northfield vs North Miami
Two of the founding members of the TRC, Northfield and North Miami had the longest conference rivalry until North Miami left the TRC in 2024.
Around 14 miles apart and sharing Wabash/Miami/Grant County borders, Southwood and Oak Hill started out as Mid Indiana Conference rivals until Southwood left in 1976. The rivalry moved to the TRC when Oak Hill joined the conference in 1980. Though Oak Hill left the TRC in 2006, there is still bad blood to this day.
- Rochester vs Tippecanoe Valley
From 1987 to 2023, these two schools often fought for conference supremacy in multiple sports.
In football, the two schools battle for The Bell traveling trophy.
Though rivals in all sports, the Peru vs Logansport football game is the oldest rivalry in Indiana high school sports.
They battle for the Baldini Trophy. The trophy is named for Don Baldini, a Peru native who became Logansport's winningest football coach.
- Whitko vs Columbia City and Churubusco
These schools are Whitley County rivals in multiple sports.
- Whitko vs Tippecanoe Valley
Both schools share territory in Kosciusko County and were TRC rivals from 1976-2023.
Western Howard County schools that are only 8 miles from each other and a rivalry that used to be played when both schools were in the Mid Indiana Conference and Hoosier Athletic Conference.
Conference
- Lewis Cass vs Northwestern
An old rivalry that is the newest to the TRC, these two schools' hatred followed them from their two previous conferences, the Mid Indiana and Hoosier Athletic Conferences.
Miami County rivals and previously Mid Indiana Conference foes until they moved to the TRC in 2015.
Maconaquah and Southwood were old MIC rivals in the 1960s until Southwood moved to the TRC in 1976. The rivalry was renewed when Maconaquah joined the TRC in 2015.
Starting in 1957, this is the oldest existing rivalry between Wabash County schools.
Only 12 miles apart, the two share Whitley/Wabash county borders.
When Wabash County schools consolidated in 1962, the smaller schools merged into two identical 'sibling' schools. This connection has made Northfield vs Southwood a natural and long-standing county rivalry.
Both schools were charter members of the Northern Lake Conference in 1963. Manchester left the NLC in 1976. When Rochester moved to the TRC in 1987, the old NLC rivalry was renewed.
The closest schools in distance in the whole TRC (only 5 miles apart) creates a very familiar rivalry.
