This is a 12-week half marathon training program that designed to prepare you to finish a half marathon race. This program will prepare you finish a half marathon and run the entire distance. It is not intended to train you to run a fast race or to improve your speed. You should be able to run comfortably for 5km before starting this program. If you have not run before, complete the "8-week beginners program", followed by the "easy 5km program" before starting this program. If you have some experience running, but cannot run 5km, gradually build up to that level with a period of base building, composed of easy running, before starting this program. You should get a physical exam and consult with your doctor before beginning any exercise program.
All workouts in this half marathon training program are easy runs. Easy runs should be at a pace that feels fairly comfortable. You should be breathing hard, but should be able to carry on a conversation. If you are breathing so hard that you cannot talk, you are running too hard. If you can sing, you are running too easily.
On the days that call for rest or cross training, you can rest or do an activity other than running. You could go for a walk, swim, cycle or do nothing. This program uses Monday as a rest day because Sunday is your longest run of the week. You can adjust this to meet your needs but be sure to take off the day after your longest weekly run.
