Our 4-part adventure series, core4winds. Each route departs to the North, East, South, or West from the center of Iowa City + features ALL the surfaces. Ride to earn a badge of honor (aka sticker) for each adventure! Simply show your Strava or RWGPS route at @SBB, @WOB, @Geoffs, or the @Bike Library to get the corresponding route sticker. Collect all 4 winds stickers to complete the core4 logo pillars! Once you’ve gathered the full core4 winds logo, snap a pic email us to be registered to win the ultimate surprise + delight: a heli ride with the SkyKing on race day.

This series is FREE to all + the ultimate core4 training tool! Do it solo or with your riding buddies every way the 4 winds blow! Join the core4 Strava group while you’re at it. This is your time to tag + brag!
