Explanation of Jeff Galloway half marathon training schedule terms

Run: When the workout includes the word "run," such as "3 mile run" or "30 min run" you should run that distance (or time interval) at a comfortable pace for you. A "comfortable pace" means one in which you could hold a conversation with someone running next to you without any difficulty breathing.

MM: This stands for "Magic Mile," which is Jeff Galloway's formula used to predict the pace at which you can comfortably run a half marathon. Think of the Magic Mile workouts as an ongoing calibration mechanism for your training. On a Magic Mile day, you need to run one mile at a good, hard pace for you. Then, take your mile time and multiply it by 1.2 to get your "Magic Mile" time, which is the pace that Jeff Galloway's formula predicts you can run a half marathon comfortably. For example, if you run your mile time trial in 8 minutes, 0 seconds, then your Magic Mile time is (8 min) * 1.2 = 9.6 min = 9 min, 36 sec. You can use your Magic Mile time to adjust the intervals of your walk breaks.

"800": In the time goal half marathon training program, there are weeks where you will be asked to do a speed workout instead of a long distance run. For example, in week 4, the Sunday time slot shows "4 x 800." What this means is that you should run four 800 meter runs around a track. These "speed" workouts allow you to practice running at the pace you would like to run the race.

You can use Jeff Galloway's Magic Mile formula to determine what pace to run your 800 meter workouts. Your training pace can be calculated by dividing your Magic Mile time by 2 and then subtracting 15 seconds. For example, if your mile time is 8 minutes, then your Magic Mile time is (8 min *1.2) = 9 minutes, 36 seconds. Hence, your 800 meter pace is ((9 minutes, 36 seconds) / 2) - 15 sec = 4 minutes, 33 seconds.

When you do your 800 meter workouts, warm up by walking for 5 minutes, then jog very slowly for 5-10 minutes. Then do between 4 and 8 acceleration-gliders. Here is a video with Jeff Galloway demonstrating how to run an acceleration-glider:

After you finish your acceleration-gliders, begin to run the 800s. Walk for 10-30 seconds after the first 400 meters (but keep your stopwatch running), then re-accelerate back to your goal pace and finish the rest of the heat. Finally, walk between 2.5 and 3 minutes before starting the next 800 meter run.

Miscellaneous training tips

  • You can never run too slow. Focus on your endurance, not your speed!
  • Use Jeff's Magic Mile prediction formula to decide on your training pace.
  • It's fine to do other exercise on Monday, Wednesday and Friday as long as it's not running. If you're weightlifting in the gym, don't do any exercises that stress the calf muscle.
  • Slow your pace down by 30 sec/mile for every 5 degrees that the temperature is above 60 degrees Fahrenheit.
