Mixed-surface riding (often called “gravel riding”) is one of the fastest-growing trends in cycling. Outside urban areas, many roads in our region are unpaved. They’re usually quieter, and drivers you meet on these roads are often respectful. When you leave the pavement, you also unlock stunning scenery and new areas around the National Capital to explore.
“Gravel” can mean many different surfaces from smooth, easy hardpack to rough, unmaintained roads and single-track in remote areas.
OBC offers a wide range of mixed-surface rides, and we lean toward routes that welcome riders who are new to gravel. Each ride listing explains the ride style, recommends a minimum tire size, and flags any remote sections or rough, unmaintained roads. We also encourage a “stop and enjoy” approach so expect time to take photos and appreciate the scenery.
On more advanced rides, you may need to walk your bike in places. You might also get wet crossing streams or riding muddy sections, even on dry days.
Because gravel rides often go through more remote areas, you should come prepared and self-sufficient. Bring two spare tubes (or a tubeless repair kit), a pump or CO₂, and a multi-tool. Food and water stops can be limited, so pack enough for the full ride.
We strictly follow OBC’s no-drop policy on gravel rides. Therefore, always tell the ride leader if you need to leave otherwise the group may stop and search for you.
Bikes
A gravel bike works best, but endurance road bikes, cyclocross bikes, and traditional touring bikes also work well. As a general guide, aim for 32mm tires or wider, and 38–42mm often feels ideal. However, many routes also work with 28mm tires if they have some tread. Gravel roads often include steeper climbs, so smaller gears help.
Pedals and cleats
Mountain-bike style cleats (for example, Shimano SPD) or flat pedals work well on rougher surfaces. They make it easier to unclip quickly and to walk when needed.
Tire pressure
Wider tires run at lower pressure, which improves comfort and traction on rough terrain. Check the pressure range printed on your tire sidewall and choose the lower end of that range for a smoother ride.
Group pace
Mixed-surface riding is slower than road riding. Groups ride at the pace of the slowest rider, and faster riders stop as needed so everyone stays together. OBC does not use fixed gravel speed groups; instead, each ride description explains the expected pace and difficulty. Most regular gravel rides remain accessible to newer and recreational riders.
How gravel rides differ from road rides
We keep groups smaller (typically 6–8 riders).
Riders usually spread out instead of riding in a tight pack, so everyone can maneuver safely.
On quiet roads, the group may use more of the lane; however, stay right on blind curves and hills to avoid oncoming vehicles (including tractors and 4x4s).
Riders may separate on climbs or technical sections, so we regroup often.
Many riders prefer not to eat or drink while riding on gravel, so we take more frequent short stops for water, photos, or quick chats.
