Winter Trail Fest (WTF) 13.1 and 5 Mile Westside

Sat March 6, 2021 Grand Rapids, MI 49525 US Directions

We at Trivium Racing are working hard to make sure we have a great event for you in March. While planning continues, athletes should be aware that the potential for cancellation or postponement still exists due to Covid-19. There are also certain modifications that will be made to mitigate the health risks posed by large group events if the event does go forward. Trust that we will do everything we can to have a safe and fun event as promised. Please make sure you are aware of our refund policy prior to signing up. We hope to see everyone on March 6, 2021!

February 23, 2021 Update: The race is a go for an in-person race starting in size-limited waves. The race will be moved from Yankee Springs to Robinette's Apple Haus and Winery. This will be a two loop half marathon course, and a 1 loop 5 mile course. We are working on updates and event details this week as we transition to the new venue. THANK YOU so much to Robinette’s for taking us in!!
February 4, 2021 Update: Registration limits for this event have been reached. Until we receive further guidance from the state that would allow for a larger group, registration will be suspended and a waitlist will be put in place. If you would like to get a spot if we are allowed to increase the event size, please sign up for the waitlist!
January 21, 2021 Update: The State Parks will be making updates to current policy at the end of January once new guidelines are released by the state. We are in constant communication with the authorities to see how that will affect our event. It is very likely that the race start will need to be broken into waves, but we will make the call on that after February 1st. You can check out our current contingency plans here. If we are not allowed to have the race in February, we do have an in-person make-up date scheduled for December 5th. 

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 Yankee Springs 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 custom 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!

New in 2021, you can race with us again in June for the Summer Trail Fest Ultra and Half Marathon and earn a matching medal to make one complete medal! With both medals in hand, it will be easy to say, WTF, I might as well STFU and Run in 2021!
