Progress against the field
From Johannesburg 2025 to Cape Town 2026, Mmathabiso Khalema and Diteboho Khalema got 5:13 faster than the field.
Over the same races everyone got 15:42 quicker, so 20:55 faster on the clock looks better than it was.
The biggest step was Johannesburg 2026 → Cape Town 2026: 3:29 on the field in 76 days.
How this is worked out ⓘ
A finish time moves for two reasons: the athlete, and the race — its course, its floor, its day. For each pair of races in a row in one category, we take everyone who raced both and use the middle of how much they moved (the median) as "the race". Whatever is left is the athlete. Doubles are compared only when the same two people raced both, and told as the pair's; relays are left out. A pair with fewer than 15 athletes in common is not shown.
