Winter Trail Fest 13.1 and 5 Mile Eastside


Please Click here to see our procedure for event modifications for this event

We will be working closely with the state to implement all necessary Covid measures to have a safe in-person event.  Modifications may include removal of post race activities, wave starts, and modified courses.  We cannot predict what December will look like in terms of the current pandemic, but we are committed to doing everything we can to host a live event.  Please make sure you are aware of our refund policy (found both on the registration page and under our rules page) prior to signing up.  We hope to see everyone in December!

For years the west side of the state got to have all the fun in the winter.  This year The Winter Trail Fest will also be coming to the East side!  We will be running 13.1 or 5 miles at our favorite winter running location, Island Lake State Recreation Area!

Some call it Whiskey Tango Foxtrot Half, some call it The Winter Trail Fest Half, some just think What The F…..  This race is not for the weak of heart or the cold intolerant. We will be down at Island Lake for a winter trail half marathon race and we will be hoping for some of the nastiest conditions possible!  We really want you to earn your WTF Medal and WTF hoodie!  The afternoon start will give you a chance to relax and enjoy the morning before tackling 13.1 brutal miles in the afternoon!

Not quite ready for a Half Marathon but still want to race?  There is also a 5 mile option!!

As with all of our races, Trivium is going to give you the best race experience possible with easy to follow trail markings, lots of aid on the course, live results, and unique prizes!

Our 2021 WTF Medal will magnetically connect to our 2021 Summer Trail Fest Ultra and Half Marathon medal!!
