MammothMarch Michigan

The MammothMarch Michigan returns to Shelby Township in Michigan on August 15th, 2026. The race offers a challenging 20-mile hike through Stony Creek Metropark, which sprawls across more than 4,400 scenic acres of diverse landscapes including woodlands and prairies less than an hour north of Detroit.
Race morning finds the park lush with greenery and awash in natural beauty. Early risers can expect temperatures to hover around a comfortable average of 20.5°C, though humidity might make it feel slightly more muggy with a typical reading at 74.7%. The terrain is varied—trail runners will navigate through wooded areas and prairies before finishing on expansive fields.
The event has been running for several years now, building an enthusiastic community of nature lovers and long-distance hikers who come together to tackle the challenge. This year's edition promises to be just as exciting with participants expected in large numbers, contributing significantly to the local community spirit.
In terms of course layout, runners will start at the parking lot near Stony Creek Metropark’s main entrance on West Road, Shelby Township. The 20-mile route is laid out across a mix of trails and fields offering scenic views throughout. There are no specific elevation details in the data provided; however, participants can expect some uphill sections as they traverse through different terrains.
Weather conditions will likely feel similar to an average day at this time: temperatures ranging from 15.9°C to 25.1°C with a comfortable feels-like temperature of 20.5°C. Wind is expected to be around 10.7 km/h, which should not significantly impact the race.
