Your sports watch gives average pace and heart rate curves, but won't tell you why you bonked in the second half, which 5K segment is your weakness, or how to adjust your strategy. You need deeper insights, not more data.
Horizontal bar chart for every 5K split. Instantly see which segment was fastest and where you faded most. Color-coded faster/slower than average.
First half vs second half pace comparison with fade percentage. Was it a perfect negative split, or a second-half collapse?
Compare pace across multiple races of the same distance. Line charts reveal your growth trajectory — improving or declining, data doesn't lie.
Scientific metrics quantify your pacing consistency, from C to S grade. The goal: "Even-Pace King" — the most efficient marathon strategy.
