Arctic Frog Run (IL)
December 6th 2025
Libertyville, IL
50 KM
“Arctic Frog” Endurance Run is a beginner’s Ultra marathon. This scenic course features a trilogy of pavement, wooded and crushed limestone trails that runs North and South of Des Plaines River (DPR) and Northwest Casey Trails. Make NO mistake- it will NOT be a “gimme” with a few challenges in stow (rolling hills) but fair! What's more, if lucky-this northern Chicago suburbia turns into a "Winter Wonderland" come December each year making it a unique running experience for anyone that haven’t tried running in the cold winter months!
