We get a lot of requests to provide difficulty ratings. The difficulty of a route can change from day to day depending on weather, changes in the road conditions and road damage caused by a variety of forces including wind, storms, flooding, snow, logging, forest fires and more. The difficulty experienced by an individual also depends on their off-road skills, level of fitness, bike size and amount of weight carried on the bike. For these reasons we can’t provide a rating system like a ski resort. We can help you a bit by ranking the existing BDR’s from most difficult to least difficult. Here is the list: CA, AZ, UT, CO, NV, WA, NM, ID, MA. So CABDR South is the most difficult especially if you ride the expert sections and Mid Atlantic BDR is the easiest in general terms. Although MABDR is the easiest there are still a few challenging rocky sections and the several water crossings that can get very difficult if the water is high. Also mud can be very challenging if it rains heavily. We hope this helps you in your planning. Be sure to also review the FAQ’s for each route prior to planning your trip.
