About The Race

More than an ultramarathon timed race, That Dam Hill is also London Ontario’s only certified marathon. When you complete 42.2km (26.2miles) or more during your timed race, you will automatically receive a certified marathon time. And yes, That Dam Hill is a certified Boston marathon Qualifier!

In addition to the marathon the course is also certified for the following distances: Half-marathon, 25km, Marathon, 50km, 50 mile, 100km, and 100 mile.

And don’t worry, the hill isn’t that big. If anything, it’s more of a molehill.

That Dam Hill is proud to host the 2015 Canadian championship for both the 6 hour and 12 hour timed races
