|---|---|---|
| 150 cm (4′11″) | 13.07 km · 8.12 mi | 13.01 km · 8.08 mi |
| 155 cm (5′1″) | 13.51 km · 8.39 mi | 13.44 km · 8.35 mi |
| 160 cm (5′3″) | 13.94 km · 8.66 mi | 13.88 km · 8.62 mi |
| 165 cm (5′5″) | 14.38 km · 8.94 mi | 14.31 km · 8.89 mi |
| 170 cm (5′7″) | 14.82 km · 9.21 mi | 14.74 km · 9.16 mi |
| 175 cm (5′9″) | 15.25 km · 9.48 mi | 15.18 km · 9.43 mi |
| 180 cm (5′11″) | 15.69 km · 9.75 mi | 15.61 km · 9.70 mi |
| 185 cm (6′1″) | 16.12 km · 10.02 mi | 16.05 km · 9.97 mi |
| 190 cm (6′3″) | 16.56 km · 10.29 mi | 16.48 km · 10.24 mi |
| 195 cm (6′5″) | 16.99 km · 10.56 mi | 16.91 km · 10.51 mi |
