Our History

ONERUN founder Theresa Carriere began her journey in 2010.

Cancer Strikes the Carriere Home

In April 2007, Theresa Carriere went for her annual routine physical. Although she was only 43 years old with no history of breast cancer in her family, she insisted on a mammogram. Within a few weeks after, she received a call from her doctor to start treatment resulting in a double mastectomy.

The Journey Starts

Theresa ran 100km from London to Sarnia in one day. She and the ONERUN team raised an incredible $180,000 for breast cancer research during their first year.

The Second 100km Run

Theresa ran another 100km in one day on June 10, 2011. Running this time from Sarnia to London raising a new record of $200,000 for breast cancer research.

Third Time's a Charm

Theresa completes her third 100km run. This time to support cancer care programs that assist cancer patients and their families. Theresa was joined at every km by someone within the community who would #RunForTheirSomeone and show their support by giving tribute to their loved ones.

2015

From Challenge to Triumph

Theresa runs for the fourth time. ONERUN's momentum has grown as hundreds of supporters join from across the province. Theresa continues to visit schools, motivating students to reach their potential and inspiring them to be leaders within their communities. Her message of "From Challenge to Triumph" inspires thousands.

2017

ONERUN Week Launched

The first-ever ONERUN week is launched in London, Ontario. Together with the ONERUN team, John Paul II and Justin Tiseo, ONERUN takes on a whole new look. High Schools across London host their own ONERUN event to raise funds for cancer programs. Westminster, St. Thomas Aquinas, St. André Bessette and Clarke Road joined John Paul II to raise over $100,000 for Wellspring. The event involved over 3,000 staff and students, in teams of 10, completing 100kms of their own.

2018

The 1 Million Mark

ONERUN Week grows to ten schools in Southwestern Ontario. Ten high schools help ONERUN in joining forces to battle against cancer. Together they brought ONERUN's total to one million dollars donated. The events raised funds for cancer care programs at Wellspring London and area hospitals.

2019

A Full Community Effort

This year, ONERUN raised an organization record-setting $208,792. With money going to cancer patient care programs offered through Wellspring London, London Health Sciences Centre and St. Joseph’s Health Care. The 2019 campaign included both school ONERUN events in May, as well as the return of Theresa Carriere’s fifth 100km run.

2020

100km Virtual Journey

In the organization's 10th year, ONERUN raised an incredible $150,811. With all events cancelled due to COVID-19, ONERUN adjusted by moving the campaign online. Over 1200 participants completed 100km of their own over a month time frame while fundraising for the cause. The event concluded with a single-day 100km run on June 19th.
