The levels are easy, moderate, and strenuous, and are relative only to other rides in this book. They may not be similar to ratings of rides in other locations, states, or publications. Easy rides are mostly flat but may include some rolling hills. There may be steep climbs, but they will be short and painless. These rides are geared for cyclists who ride periodically, possess good bike-handling skills, and are usually game for a small adventure.
Strenuous rides tend to go places that require the use of the granny gear along the way.
These are suited for strong bikers who ride on a regular basis, are acclimated to high elevations, and possess advanced handling skills. Endurance, power, and determination are prerequisites. Remember, these ratings are somewhat subjective and are for the purpose of comparison. Easy rides can still have you gulping for air, and moderate ones can make you walk. Compare your first rides to the levels listed to determine what trails are within your ability.
