- Your body gets bored, too. It's not just your mind that suffers from boredom when you do the same thing day after day. Your body will quickly get used to the same cardio routine and you'll hit a plateau, which means fewer calories burned per workout.
- Running up a hill is incredible conditioning. Part of the reason I enjoyed my clockwise park run was because it minimized the uphill battle toward the end of the run. But running hills increases your heart rate and helps prevent stuck-in-a-rut route boredom.
- Cross-training can be fun! When I was training for a long race I was so focused on the long runs, short runs, fast runs, and slow runs that I didn't cross-train, and I suffered through a long race with a weak core. Try Pilates to increase core muscle strength; your posture will improve and so will your running form. Plus, you'll notice those hills getting a lot easier!
