The Spotted Cow 600K is a classic two-day endurance weekend and a smart, efficient way to take a big step forward in randonneuring. Starting and finishing in Woodstock, the event features two loops that explore the quiet backroads of northern Illinois and southern Wisconsin across two distinct days.
This brevet is ideal for riders looking to set a personal best, complete their Super Randonneur series, and secure early registration eligibility for Paris–Brest–Paris 2027. Built for steady pacing and strong fundamentals, the Spotted Cow 600K offers a rewarding path into longer-distance riding—without unnecessary complexity.
Day One delivers a challenging, scenic 400K loop, while Day Two offers a satisfying 200K to bring things home. You can ride the full 600K, or complete either day independently. However you approach it, this weekend is about pushing your limits and sharing the road with good company.
Getting to Woodstock
Woodstock is easily accessible from Chicago via the Metra Union Pacific Northwest (UP-NW) Line, which runs directly from Ogilvie Transportation Center to downtown Woodstock. The station is centrally located and a convenient option for riders traveling in from the city for the weekend.
Riders are encouraged to arrive Friday night for a relaxed start to the weekend, with a team dinner and several affordable overnight options available nearby.
