When you train for a marathon, every workout you do has a specific pace associated with it so you gain the most value from it. Use these pacing guidelines for your workouts.
Recreational runners should follow these guidelines for tempo runs and intervals:
Tempo runs (runs at your tempo pace, which corresponds to your fastest sustainable aerobic pace)
About 10 to 15 seconds per mile slower than the pace you run for a 5K race
Equal or very close to the pace you run for a 10K race (if you’re slower than about 53:00 for 10K, your tempo pace will be slightly faster than 10K race pace)
80 to 85 percent of your maximum heart rate.
