Start Time: 08:30
Travel Mode: Bike, Run

Start Information:

The day begins in Hermann at the Deutschheim State Historic Site.

End Information:

The stage concludes in Marthasville at the Katy Trail - Marthasville Trailhead.

Details:

Our last full stage on the Katy Trail is a quiet one, with few communities of any size. A long stretch runs directly alongside the river, and it's worth timing a break at the Peers Store, an institution along the Katy--but check for an updated schedule in advance. The stage concludes in Marthasville, a town that is quite welcoming to ADT / Katy travelers, allowing riders and hikers to camp in the town park and make use of showers.

Support: A support vehicle will be accessible at Gore Rd (6 miles), Mertens Quarry (12.5 miles), and Treloar (15.9 miles). Water will be available to top off bottles, along with all necessary participant gear. 

Take Heed: This is one of the less-serviced sections of the Katy Trail, with few established trailheads and food only potentially available at Treloar and Peers.
