Build a race split table
The main English intent is a pace band: runners want lap or kilometer checkpoints that show split time and cumulative time for a goal finish.
ti - split time, di - split distance, Pi - split pace, Ci - cumulative time.
Even, negative and positive splits
- Even splits keep every segment close to the average pace.
- Negative splits start slightly slower and finish faster.
- Positive splits start faster and slow later; use with caution on longer races.
