Marathon Analysis Settings
Please enter your desired marathon pace (min:sec)
The system will analyze segments based on this length
How It Works:
1. The system uses your input base pace as the baseline
2. Automatically adjusts recommended pace based on each segment's gradient (slower uphill, faster downhill)
3. If you set a target finish time, the system will reverse-calculate and optimize each segment's pace to ensure total time meets the target
4. Finally displays recommended pace, speed, and estimated time for each segment, and calculates total duration
