More than a spectator friendly certified marathon race, That Dam Hill Marathon and Ultra Races is also London Ontario’s only ultra marathon timed race. If you register for a timed race, the first 42.2km (26.2 miles) you complete will automatically give you 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, Marathon, 50 km, 50 mile, 100 km, and 100 mile.

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