From the Organizer
Brrrrr... baby, it's cold outside. Good.
Around here, we don't spend winter hiding under blankets and counting down the days until spring. We get outside and celebrate it! The Waukesha JanBoree is all about embracing everything that makes a Wisconsin winter great, and the Frosty 5K is your chance to be part of the action.
A longtime JanBoree favorite and a proud stop on the Wisconsin Chilly Willy Winter Run Series, the Frosty 5K invites runners, walkers, families, and winter enthusiasts alike to bundle up, lace up, and tackle the season head-on.
The fast, flat, two-lap course winds through beautiful Frame Park and along the scenic Fox River, offering a perfect setting for PR hunters, casual runners, and anyone looking to shake off a little cabin fever. Crisp air, frozen breath, and the crunch of winter beneath your feet... this is what January running is all about.
And when you cross the finish line, the fun is far from over. JanBoree fills the entire weekend with more than 35 events and activities throughout Waukesha, creating one giant winter celebration for all ages.
Sure, it'll be cold. That's kind of the point.
Every January, hundreds of runners trade excuses for extra layers and prove that Wisconsin winters aren't something to endure. They're something to enjoy.
So zip up that jacket, pull on those gloves, and join us for a No Mopin', Nose Nippin', Cold Snappin' Good Time at the Frosty 5K!
