Pro Tips for Pace Planning
Start Slower
In races, start 10-15 seconds per mile slower than your target pace. You'll warm up and finish strong rather than fading.
Use Race Predictors Wisely
Predictions work best when you've trained specifically for the distance. A fast 5K doesn't guarantee a proportional marathon time.
Practice Race Pace
Include race-pace workouts in training. Run segments at your goal pace so your body learns to sustain it on race day.
Adjust for Conditions
Add 10-20 seconds per mile for hot weather (above 60°F/15°C). Heat significantly impacts running performance.
