11. On Some Rides, Plan to Work on Skills and Forget About Aerobic Fitness
This means you will get off the bike and complete several "do overs" on one or more sections of the trail that you want to master. When your legs get too tired to give solid effort on tough sections, call it quits for that a day.
12. Ride With Experienced Riders That Will Help You Learn to Mountain Bike on Ability-Appropriate Terrain
Riding with people who want to take you over the toughest local trails on your first six outings on a mountain bike will likely lead to a bad experience and discouragement.
Ride with people that will take the time to help you learn new skills on terrain that is appropriate for beginners. Mastering small obstacles and getting some foundation skills will help you be a better rider in the long run and lowers the likelihood that you'll get discouraged and quit.Mountain bike riding is excellent cross training for road riding. Taking a break from the road and hitting the dirt can revive waning enthusiasm and improve your overall fitness.
If you're tired of the road, consider getting dirty.
