Running a 10K (that's 6.2 miles) can be intimidating, but if you can run 3 miles or 30 minutes comfortably, you can definitely do it.
This program will help you build a base to run a 10K in six weeks with a mix of running, strength training, and cross training. Be sure you are using proper running form  to help you conserve energy, improve speed, and prevent injuries.
Tuesday and Sunday runs: Warm up with a 1-mile easy jog. Run the remainder at a comfortable steady pace.
Strength training: Complete all the exercises in Circuit 1 consecutively with minimal rest. Repeat for a total of three circuits, then continue with all the exercises in Circuit 2, again performing three circuits total.
Cross-training: Chose any type of cardio other than running, such as swimming, cycling, elliptical, stair climbing, rock wall climbing, or fast walking.
