From the Organizer
The White Pine Thaw Marathon Relay will be Sunday, March 7th, starting in Comstock Park, Michigan, on the southern most section of the Fred Meijer White Pine Trail. It's held annually on the second Sunday of March. Competitors form teams of runners and on race day, will each take a leg of the relay, covering 13.1 miles, north to Russel Road, where the course returns back south to Comstock Park. There are easily accessed parking lots and bathrooms, roughly every four miles. The trail is routinely plowed by Friends of The White Pine Trail and covers very few low traffic crossroads.

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
