"Having secured a title sponsor provides us with the long-term financial footing that will allow us to make the weekend even more enjoyable for our 40,000 runners," stated Jim Robinson, the event's race director.
"We can explore ways to grow the event, improve runner amenities, and build on our already respected status with the local, national and international running community."
Financial details were not disclosed. ING Canada had pulled out as title sponsor in 2008.
In a previous OBJ interview, he noted the marathon had made do by removing items that were not integral to the experience of the runner.
Sponsorships declined to 10 per cent of revenue from 25 per cent during the period, but the operating budget remained consistent at $2 million. This was partly due to the loss of the title sponsor, and the growth in new entrants to the weekend.
"We are holding our own, and that's good; it's showing that we're financially responsible," he said.
The newly named Tamarack Homes Ottawa Race Weekend will take place May 26-27, 2012.
