Wirth on Wednesdays

Mountain Bike Race Series

Wirth on Wednesdays (WOW)

A spotlight shines bright on the Loppet Foundation-managed singletrack trails at Theodore Wirth Park with the return of the popular spring and summer mountain bike race series. Meet us at The Trailhead for the 2023 Wirth on Wednesdays (WOW) events.

The Trailhead at Theodore Wirth Park has some of the most accessible trails around, including the popular Conundrum, Area 36, 45 North singletrack loops, all linked by the amazing paved trail network composed of the Grand Rounds, Theodore Wirth Parkway, and Luce Line trails.

Saddle up and get ready to ride in this fun race series that will surely WOW you!

There is no in person registration, all registration MUST be done online. This can be done via a mobile device right up to race time.
