Long run to 45 min. Easy runs stay at 25 to 30 min. About 12 miles total.
Long run to 50 min. Add a few 1 min pickups to one easy run. Getting stronger.
Long run to 60 min (about 5.5 to 6 miles). You just ran an hour. Big deal.
Long run drops to 45 min. Easy week. Let the body catch up.
Long run to 70 min. Add one 15 min tempo at a brisk pace. About 16 miles.
Long run to 80 min (about 7 to 8 miles). Practice eating a gel during the run.
Long run to 90 min (about 8 to 9 miles). You are now running serious distance.

Two easy 20 to 25 min runs. One 15 min shakeout with strides. RACE DAY!
Key Workouts
Long Run
Your weekly long run is the most important workout. Run at a comfortable pace where you can talk easily. Walk if you need to. Just keep moving.
Easy Runs
Short, comfortable runs of 25 to 35 minutes. These build aerobic fitness without taxing your body. Keep the effort light.
Pickup Run
During one easy run, add 4 to 6 surges of 1 minute at a faster pace. Not sprinting, just brisk. Keeps your legs sharp.
Common Mistakes to Avoid
Increasing long run too fast
Never add more than 10 to 15 minutes to your long run per week. The plan handles this for you.
Not walking when needed
Walking is allowed and encouraged. Many first time half marathon finishers use a run/walk strategy.
Not practicing nutrition
Start practicing gels or energy chews on long runs over 60 minutes. Figure out what works before race day.
Setting a time goal
Your first half marathon goal is to FINISH. Time goals add pressure you do not need. Save them for the second one.
Race Day Strategy
Start at the back of the pack. Run your comfortable pace for the first 5 miles. Walk aid stations if needed. Pick it up slightly in the last 3 miles if you feel good. Enjoy the crowd. Cross the line proud.
Nutrition Tips
Eat a simple breakfast 2 to 3 hours before (toast, banana, oatmeal). Take a gel at mile 5 and mile 9. Drink water at every station. Do not skip aid stations.
