Carpe Diem - Carpe Noctem Half Marathon and 10K - MI

Seize the day and conquer the night at the Carpe Diem - Carpe Noctem Half Marathon and 10K, an unparalleled trail experience hosted by Trivium Racing on Saturday, April 11, 2026. Set within the breathtaking Proud Lake State Recreation Area in Commerce Charter Township, Michigan, this unique event challenges runners to embrace the trails in both daylight and under the stars. Choose your adventure from a morning or evening Half Marathon (13.1M) or 10K. For the ultimate test, take on the "Double" challenge by running both a morning and evening race, allowing you to achieve distances of 20K (two 10Ks), 26.2M (two Half Marathons), or even a challenging 19.3M combination.

The well-marked and wide trails of Proud Lake are generally beginner-friendly, offering a runnable course with some roots and "some hills" to keep things engaging. Prepare for the possibility of classic Michigan spring mud if there's rain, adding an extra element of fun to the picturesque scenery. Aid stations are strategically placed, with the Half Marathon offering six waterstops stocked with water, Gatorade, and Huma Gels, while the 10K provides two waterstops with water and Gatorade. Typical race day conditions in mid-April feature highs around 55°F and lows around 35°F, with a 13% chance of precipitation, providing ideal running weather.

Beyond the unique format of day and night running—with headlamps required for evening finishers—the Carpe Diem - Carpe Noctem fosters a vibrant community atmosphere. Between the morning and evening races, participants are invited to a full-day trail hangout, complete with hot food, a potluck, and lawn games, creating a festive environment to connect with fellow runners. All registrants receive a cozy race hoodie, and those who conquer the "Double" earn two gorgeous medals that magnetically connect to form one epic keepsake. This event promises not just a race, but a memorable and engaging day on the trails.
