About the Carpe Diem - Carpe Noctem Half Marathon and 10K - MI
The trails at Proud Lake State Recreation Area are wide and runnable, with occasional roots and the possibility of spring mud. What makes this race unusual is the format: you can run the same course in full daylight, return in the evening by headlamp, or do just one. The evening races begin before sunset and carry well into dark, the woods feeling entirely different at night.
Packet pickup happens on-site before each race, with no early option the day before. Parking is at the campground entrance, not the main park gate, and entry requires a state recreation passport collected at the gate. Between the two races, there is hot food, a potluck, and lawn games for anyone who wants to hang around.

The Carpe Diem - Carpe Noctem Half Marathon and 10K - MI has been held every year since at least 2018. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 25, 2026.
