The Gritty

Another route to test your inner endurance adventurer, this route from a now-defunct race called the Gritty Brevet combines the flatter southeast quadrant of Johnson County with the rollers in the western part of the county. From the Johnson County Fairgrounds (site of the famous Jingle Cross cyclocross races!), you’ll head generally east and south first to get good and warmed up. Then you’ll head west, arriving at Riverside, future home of Star Trek’s Captain James T. Kirk (really!), about 45 miles into your journey. As you make your way farther west and gradually north, the traffic on the road will likely include the horse-drawn buggies of the local Amish farm families. Your next opportunity for convenience store refreshments won’t come until you reach Tiffin at 86 miles into the adventure, so be sure to bring along plenty of water and food to get you through. After all the work on the rolling hills, you’ll end your ride with a final, fun descent.

Jingle Cross Cyclocross Races

There’s nothing quite like the excitement of these three days of cyclocross racing, from amateurs to pros, from local to international, from kids to dogs, all on a course and at a venue that has consistently been ranked among the favorite of World Cup racers. Race or heckle under the lights on Friday night, and keep it going all day Saturday and Sunday as racers give everything they’ve got to get up Mt. Krumpit, take their bike-handling skills to the limit on treacherous descents and the sand pit, and deal with the unpredictable conditions Iowa weather throws at them. You’ll be up close and personal with cycling heroes and celebrities, thanks to the Herculean efforts of dedicated local volunteers who make it all happen. There is no other sporting event like cyclocross—come experience it for yourself!

Mountain biker riding down rough terrain at Sugar Bottom Trails

Sugar Bottom

One of the premier mountain biking destinations in Iowa is located in the midst of hardwood forest along the Coralville Lake, just north of Iowa City and between North Liberty and Solon. The Sugar Bottom mountain bike trail system, in the Sugar Bottom Recreation Area, includes roughly 12 miles and 1,400 climbing feet of outstanding hand-built trails. The one-way trails range from beginner to expert and are configured in a stacked loop system. You can enjoy a green ride on a continuous loop through the whole system, or check out the blues and blacks that loop off of the main trail. Along the way, you might hear the calls of barred owls, startle a group of deer or turkeys, or see an osprey working on its nest.

Races are held at the trail system several times a year and draw riders from across the Midwest.

Trail status is updated here and via signage at the trails; fines are imposed for riding closed trails.

Camping is available at the Sugar Bottom Recreation Area, along with disc golf, a beach area, playground, barrier-free asphalt trail, nearby boat access, and more. There is plenty to do between mountain bike rides!

Westward Ho!

This ride will give you a chance to fully experience the rolling topography of western Johnson County and beyond in a lollypop-type route. You’ll head west and west, then turn north. You won’t have to navigate many turns until the route heads back east. At roughly miles 27 and 39, you’ll arrive at towns with some C-store options if you’re in need of refreshment, and in between you’ll pedal along the edge of Kent State Park, a hilly gem in the countryside.

Devonian Fossil Gorge

Turn Here!

Feet of Climb

This is another shorter route for the Advanced Adventure routes, and its challenge lies in two characteristics: significant climbing and punchy hills, and a lot of turning. Bring your cue sheet! The good news is that you’ll come across plenty of options for a refueling stop if needed in Coralville and North Liberty—or just at your start-finish point. This route takes you across the Coralville Dam Spillway. During severe flooding in 1993, water rushed over the spillway and uncovered a prehistoric treasure trove in what is now called the Devonian Fossil Gorge. You might stop and look around!
