2026 reference edition · Up Run
Comrades qualifier calculator
Check a marathon or ultra result against every published 2026 qualifying cutoff, see the official start-group guideline, and turn a recent marathon into separate Up and Down Run finish-time ranges. No sign-up, and the result stays in your browser.
The result must appear in the race organiser’s official results. The 2026 rules explicitly rejected watch, Garmin and Strava records, even when the recorded distance and time were valid.
This is the group guideline, not an exact letter batch. In 2026 the CMA ranked submitted marathon or equivalent times from fastest to slowest inside the groups. Field size and special Batch H placements affected the final letters, so a fixed A/B/C time table did not exist.
This is Ross Tucker’s broad model: marathon time × course distance ratio × 1.10–1.15. It assumes specific ultra preparation. The Up and Down values differ because the verified editions had different distances; the formula does not pretend to measure your climbing strength or downhill durability.

The complete 2026 qualifying table
Comrades did not use one universal five-hour rule for every race distance. The standard marathon cutoff was 4:59:59, while longer official races had their own cutoffs. A 56 km result, for example, had to be 6:59:59 or faster. Selecting the row that merely looks closest to a race is not enough: the official race distance must match the listed distance or the 52–54 km band.
| Official race distance | 2026 qualifying time | Average pace at cutoff |
|---|---|---|
| 42.2 km | 4:59:59 | 7:07/km |
| 48 km | 5:59:59 | 7:30/km |
| 50 km | 6:09:59 | 7:24/km |
| 52–54 km | 6:29:59 | 7:30/km–7:13/km |
| 56 km | 6:59:59 | 7:30/km |
| 60 km | 7:39:59 | 7:40/km |
| 64 km | 8:14:59 | 7:44/km |
| 80 km | 10:34:59 | 7:56/km |
| 90 km | 11:59:59 | 8:00/km |
| 100 km | 13:34:59 | 8:09/km |

What counted as a qualifier
For the 2026 edition, the qualifying performance had to be run between 9 June 2025 and 4 May 2026. The race had to be technically compliant, at least 42.2 km, and verifiable through the organiser’s official results. South African athletes also needed a 2026 permanent licence and club details; every entrant had to complete the medical questionnaire.
A watch file was never a substitute for an official result. This matters for races where GPS reports 42.2 km but the event itself is not certified or where an athlete records a faster moving time than the published finish time. The calculator checks the numbers you enter, but only the CMA could verify and accept the result.
Why this page shows a group, not an exact batch
The 2026 race introduced three start groups. As a guideline, runners faster than 4:03 marathon-equivalent went to Group 1; 4:03:00 through 4:32:59 went to Group 2; and 4:33:00 through 4:59:59 went to Group 3. The groups started at 05:00, 05:15 and 05:30 respectively.
| Guideline | Time band | Batches | Start |
|---|---|---|---|
| Group 1 | under 4:03:00 | A–G | 05:00 |
| Group 2 | 4:03:00–4:32:59 | H–M | 05:15 |
| Group 3 | 4:33:00–4:59:59 | N–R | 05:30 |
Those times did not define Batch A, B, C and so on. The CMA first ranked the accepted qualifiers from fastest to slowest, then divided them among the letter batches. Group 2 also contained a special Batch H for qualifying Green Number and Race4Charity runners. That is why an exact batch calculator built from time alone would be false precision.
Reading the finish-time range
The finish estimate uses a range suggested by sports scientist Ross Tucker: recent best marathon time multiplied by the ratio of Comrades distance to 42.2 km, then multiplied by 1.10 at the fast end and 1.15 at the slow end. A four-hour marathon becomes roughly 8:57–9:21 over the verified 85.777 km 2026 Up Run route.
This range is not a qualifying rule and it is not issued by the CMA. It assumes that the marathon reflects current ability and that the athlete completes Comrades-specific preparation. A soft qualifier, a fast downhill marathon, cool race conditions or a large gap between the qualifier and Comrades can all make the estimate optimistic. The longer the target race, the more training history matters than one conversion formula.
Up and Down are different races
The 2026 Up Run travelled 85.777 km from Durban to Pietermaritzburg. The 2025 Down Run travelled 89.98 km in the opposite direction and finished in Durban. Exact distances change when the route or finish venue changes, which is why the calculator labels each value with an edition rather than claiming that every future Up or Down Run has that length.
“Down” does not mean easy. The long descents create repeated eccentric loading in the quadriceps, and runners without downhill conditioning can lose their stride late despite a lower finish elevation. The Up Run demands sustained climbing and conservative effort early. The estimate only captures the verified distance difference. It deliberately does not add an invented universal hill penalty, because the effect depends on training, body mass, pacing and the exact route.
Qualifying is not the same as being ready
A result can satisfy the entry table and still leave a difficult twelve-hour day. The qualifier proves that an athlete crossed one published threshold. It does not prove durability over twice the distance, nutrition tolerance, heat management or the ability to keep moving after several major climbs. The official 2025 finishers programme explicitly warned that a sub-five qualifier did not guarantee a finish.
Use the cutoff margin as a diagnostic. A large margin gives more room for a controlled Comrades pace, while a result close to the cutoff makes consistency, conservative pacing and long-run progression especially important. It is not a reason to rush mileage. An injury from forcing the qualifier has no value on the start line.
Sources and version notes
Qualification cutoffs and the 9 June 2025–4 May 2026 window come from the Comrades Marathon Association FAQ for the 2026 edition. The start-group boundaries, batch ranges and start times come from the CMA’s May 2026 seeding announcement. The verified course distances come from the CMA’s race reporting for the 2026 Up Run and 2025 Down Run.
The 1.10–1.15 finish range is separate: Runner’s World South Africa published it in 2024 with Prof. Ross Tucker’s caution that individual physiology and preparation make hard predictions unreliable. The page keeps that warning attached to the number.
