Tamarack Ottawa Race Weekend
Races
Challenges
From its humble beginnings in the 1970s to its status as Canada’s largest multi-race running festival, the Tamarack Ottawa Race Weekend has a rich history deeply intertwined with the growth of distance running in North America.
Here is the story of how a small local race transformed into a world-class, multi-day athletic tradition.
The Humble Beginnings: 1975–1979
The event was born out of a simple realization: local runners from Ottawa kept bumping into each other at out-of-town races and decided the nation’s capital needed its own event. Founded by local running enthusiasts—including legendary coach Ken Parker—the inaugural National Capital Marathon took place on May 25, 1975.
- The First Field: The inaugural race saw just 146 finishers (143 men and only 3 women). It started and finished at Carleton University.
- The Olympic Trials (1976): In just its second year, the marathon’s reputation for pristine organization earned it the right to host the Canadian Olympic Marathon Trials for the 1976 Montreal Olympics. Wayne Yetman won the race in a course-record $2:16:32$, booking his ticket to the Olympics and famously earning a luncheon with Queen Elizabeth II.
Evolution into a “Race Weekend”: 1980s–1990s
As running exploded in popularity throughout the 1980s and ’90s, the event expanded beyond just a single 42.2-kilometre race. It transitioned from a hardcore marathon into a community-wide festival by adding accessible distances.
- 1986: The 10K distance was introduced, which would eventually become one of the fastest and most prestigious 10K races in the world.
- 1996: Jim Robinson took over as Race Director, kicking off a 17-year tenure that stabilized the race’s finances and drastically expanded its infrastructure.
- 1998: The 5K and Half-Marathon distances were introduced. That same year, Ottawa made history as the first running event in Canada to implement electronic chip-timing. It was also the year “Pace Bunnies” (pacers) were introduced to help runners hit their goal times.
- 1999: The 2K distance was added, solidifying the multi-race weekend format.
Going Global and “Tamarack” Era: 2000s–2010s
By the turn of the millennium, the finish line had moved to Ottawa City Hall, and the event routinely drew tens of thousands of athletes.
- The Rebrand (2009): The parent organization changed its name to Run Ottawa to better reflect its year-round dedication to the local running community.
- The Title Sponsor (2012): Two-time Olympian John Halvorsen took over as Race Director. Under his leadership, Ottawa-based developer Tamarack Homes signed on as the title sponsor, officially naming the event the Tamarack Ottawa Race Weekend.
- World Athletics Elite Status: The event achieved massive international prestige by becoming one of the few running festivals in the world to host two World Athletics (formerly IAAF) Gold Label events: the Ottawa 10K (awarded Gold in 2014) and the Ottawa Marathon (awarded Gold in 2015).
- Record Growth (2014): Celebrating its 40th anniversary, the weekend hit a peak registration of nearly 48,000 participants across all events.
Resilience and Modern Era: 2020s–Present
Like major road races worldwide, the Tamarack Ottawa Race Weekend faced unprecedented challenges at the turn of the decade but emerged stronger.
- The Pandemic Interruption (2020–2021): For the first time in its history, the in-person races were canceled for two consecutive years due to the COVID-19 pandemic, forcing organizers to pivot to virtual events.
- The Golden Jubilee (2024): The Ottawa Marathon celebrated its monumental 50th anniversary in May 2024. The event also set a record for its Desjardins Charity Challenge, raising over $1.1 million for local and national charities.
- Today: Now under the direction of Ian Fraser, the weekend remains Canada’s premier running festival. It functions as a Boston Marathon qualifier, hosts the Canadian 10K Championships, and brings more than 100,000 spectators to the streets of Ottawa and Gatineau every May.
Did You Know? The current men’s marathon course record is held by Ethiopia’s Andualem Shiferaw, who flew through the capital’s streets in 2:06:04 in 2022.
