Carpe Diem - Carpe Noctem Half Marathon and 10K
The event takes place Saturday, April 11, 2026 at Proud Lake State Recreation Area in Commerce Township, Michigan. It is a trail race with both morning (daylight) and evening (nighttime) occurrences. Options include running a single event in the morning or evening, or a Double that combines day and night versions of the same distance. Evening races start just before sunset and many finish after dark. Runners who complete both the day and night events receive two medals that magnetically connect into one piece.
