About the event

Attention | New Course Description | New 50 MILE Distance

“Arctic Frog” Endurance Run has been MOVED to Mayville, WI. It is roughly one (1) hour and forty (40) minutes from Libertyville.

This new course is roughly 20% trail, crushed limestone gravel and mostly asphalt, but while we advertise it as a “beginners” Ultramarathon - make NO mistake - it will NOT be a “gimme”! We definitely have a few challenges in store (rolling hills) for you! What's more, if lucky - this hidden gem of northwestern Wisconsin turns into a "Winter Wonderland" come December each year, making it a unique running experience for anyone that hasn’t tried running in the cold winter months!

**BTW, we also just added a 50 Mile distance to this race in case you feel 50k isn't enough of an adventure for you. Hurry and sign-up!

Anyone already registered for this race, you have a few options. They are:
a. defers to Arctic Frog 2021 - we will give you credit up to 50% of the registration fees
b. opts to run virtual Arctic Frog 2020 - we will mail you your swag
c. be a real bad ass by showing up in Mayville, WI December 5, 2020 for a new kind of adventure

Drop Bags

There will be a tarp at the start/finish for drop bags. We will not be transporting any drop bags to any locations on the course.

What To Wear | Recommended Gear

AS Tents will have “heaters” but come ready for COLD weather and running in the snow regardless of the weather forecast. Bring EXTRA clothes, socks and another pair of running shoes. This is Wisconsin after all … The weather does turn for the worst rather quickly!

If running the 50 miler, I suggest you bring a “headlamp” with “extra batteries” in your drop bag.
