ONE OF AMERICA'S CLASSIC ULTRAS

Saturday, September 11 2021

The Ice Age Trail 50 is one of the oldest continuously-running ultras in the country. A course like no other, you’ll run in dense deciduous forests, under tall pines, over rocky ridges and across open prairies – and see lakes, kettles, kames, erratics and other natural features left when the glaciers finally retreated from Wisconsin more than 10,000 years ago.

Created to bring the ultra scene to the Midwest in the ‘80s, the Ice Age Trail 50 is now a competitive hotbed.

It’s incredibly well-run from course marking to aid station operations to post-race barbecue (complete with free food, beer and tunes!).  It’s one of my favorite races and one I would recommend for everyone.

Race-day production was top-notch. Despite being one of the largest 50-milers in the country, Ice Age reminded me why I miss low-key trail races. The course was clearly marked with…flags at every turn, aid stations were well-stocked and well-spaced…and without exception the volunteers were nothing short of brilliant.

The best part about ultrarunning is that even on a rough outing, the experience is always a blast. Race Director Jeff Mallach does a phenomenal job organizing things and providing a killer post-race atmosphere. It was really easy to stick around and chat with all kinds of runners about a variety of topics. The volunteers were great.

Besides the glorious trail running experience, the other main reason to run Ice Age is for the post-race party. Lots of free beer. The food is good. And there’s nothing like sitting at the finish line cheering on your friends.
