So you’ve run a 5K, you’ve run a 10K and now you’re ready for the next challenge. Taking on a half marathon (21K or 13.1 miles) is the next step. The half marathon is a challenging distance, but it is attainable and doesn’t require the same level of training that a marathon requires.

Below is a basic 14-week training schedule that has been designed to help any runner build endurance and complete a half marathon.

Note: All training runs in this basic half marathon training program should be run at a pace that feels comfortable. You should be breathing hard, but you should still be able to carry on a conversation. Before beginning any exercise program, you should check with your doctor.
