The defining feature is not the climbing but the navigation. Nothing is marked, and the field spreads out across open mountain from the first climb to the Tower at 6.6 km; a wrong line off Avoca Peak, the high point at 2,723 m, costs hours rather than minutes. The Dragon's Back is a ridgeline barely three metres wide with steep ground on both sides, and The Wall climbs 400 m in 2.5 km. Balloch, at 56.3 km, is the only place a crew may meet a runner and one of only two bag-drop points - the other is the finish - so the 43 km from there to Wartrail are run alone with whatever is in the pack. Eleven checkpoints carry their own cutoffs, tightening through the night. The figures here come from the organiser's own pace chart, which is the only source that publishes per-checkpoint climbing; the race page quotes an approximate 4,500 m and ITRA lists 4,730 m, and that gap is unresolved.
Data is approximate and courses change between editions - always verify against the official race guide.

Who finished, 2025 edition
141 runners finished this edition.
The organiser published no finish times we can stand behind for this edition, so this page publishes the counts alone: how many finished, who they were and where they came from. No average and no median appears anywhere below, because we hold none worth quoting.

Bar length is against the largest nation. The smallest counts are drawn at a minimum visible width, so their bars are not to scale.
Edition by edition
Every edition we have recomputed in full, newest first. The course, the weather and the field change from year to year, so a slower edition is not a harder one.
| Edition | Distance run | Starters | Finishers | Finish rate | Median finish |
|---|---|---|---|---|---|
| 2025 Latest | 99.2 km | - | 141 | - | - |
| 2024 | 99.2 km | - | 125 | - | 25:34:00 |
How these numbers were computed
The counts, the gender split, the age groups and the nations are computed from the full official result list. The finish times in that same list are not consistent with each other, so we publish none of them rather than a figure we would have to hedge. Bands with only a handful of finishers move a lot from one edition to the next.
Nationality here shows who travels to this race, not who runs it best. That alone is why a host nation tops almost every list.

Talk to your race
Ask SkyRun 100 anything about climbs, pacing, crew or cutoffs.
Which climb should I respect most?
Lady Grey to CP1 Tower: +799 m over 6.6 km, straight from the gun. Hike the steep sections at an effort you could hold for hours - the race is decided after this climb, not on it.
Where can my crew meet me?
CP6 Balloch, km 56.3 - your only crew point. Have them bring warm layers: the course tops out at 2,723 m, through the night, in November.
Is 25h a realistic finish for me?
25h leaves 5h inside the 30h cutoff. It means holding 15:07/km overall.
Your long runs peak at 30 km, so the plan builds to 4-hour long runs, two of them at night. Cutoff buffer at CP5 Skidaw: 10 min.
To answer this for you, the Coach uses your training and your race plan.

FAQ
How long is SkyRun 100?
SkyRun 100 covers 99.2 km (about 62 miles) point to point, from Lady Grey to Wartrail Country Club across the Witteberg range in the Eastern Cape, South Africa.
How much elevation gain does SkyRun 100 have?
The organiser's checkpoint table gives 3,897 m of cumulative climbing and 4,505 m of descent, finishing around 600 m below the start. The race page quotes an approximate 4,500 m and ITRA lists 4,730 m, so treat any figure here as approximate.
What is the cutoff time for SkyRun 100?
The overall cutoff is 30 hours from the 04:00 start on Saturday 14 November 2026, finishing at 10:00 on the Sunday. Eleven intermediate cutoffs apply, from 2 hours at the Tower (6.6 km) to 28 hours at Halstone Peak (94 km).
Is SkyRun 100 marked?
No. SkyRun is self-navigated: the route is unmarked and runners follow GPS tracks and waypoints supplied with entry, loaded onto their own devices. It is also self-supported, so runners carry their own food and water between checkpoints.
Where can crew meet runners at SkyRun 100?
Balloch, at 56.3 km, is the only point where seconding is allowed, and the organiser runs a shuttle for crew in and out of the farm. Bag drops go to Balloch and the finish only. There is no cell reception at Balloch or at the finish.
How many people finish SkyRun 100?
141 runners finished the 2025 edition and 125 finished in 2024. The organiser publishes no starter count, so a finish rate cannot be stated.
What is the average SkyRun 100 finish time?
Across the 125 finishers of the 2024 edition the median finish time was 25:34:00 - half the field took longer than that - while the average was 25:13:33. Men and women finished within four minutes of each other at the median. The organiser published no usable finish times for the 2025 edition, so that year is shown as counts only.
