The 2021 race is now sold out! Please sign up for the wait list and you will receive a link to register if a spot becomes available. 


We at Trivium Racing are working hard to make sure we have a great event for you in April.  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 may 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 (found both on the registration page and under our rules page) prior to signing up.  We hope to see everyone on April 10th, 2021!

Seize the Day and Seize the Night in 2021 with one of Trivium's favorite events! The race will take place on the beautiful and smooth trails of Proud Lake State Recreation Area.  These trails are perfect for running both day and night and will offer a chance for lightning fast trail-race times!

The event includes both a long (Half Marathon) and short (10K ) option in the morning and evening. The morning race will be completely in daylight and the evening option will start before dark, but many people will finish after the sun has gone down!

We will have both a day medal, and a night medal. If you do both events your two medals will connect to make one complete medal.

This is a state park so to enter the state park you will need a State Park Passport (good at all parks all year) upon arrival.  This money will be collected at the gate if you do not already have one, but it's cheaper to get it ahead of time!
