Devil's Lake segment of the Ice Age Trail, from the Ronzo's Meadow parking lot to Parfrey's Glen. The route follows several trails through the very popular Devil's Lake State Park and features three significant ascents and one probably-not-runnable descent down the East Bluff. Great scenery throughout.
This follows the current route marked by the yellow blazes and on the Ice Age Trail GIS site here:
There is a Strava segment for this route, but please also report your stopwatch time.
You may jog back along the road to close the loop, but that's not part of this FKT.
