The Ringkøbing Fjord Summer Edition is a 100 km loop around the fjord that ends in the Ringkøbing Atletikstadion. It has no mountains to speak of: what makes this ultra hard is holding the same running stride for an entire day, and that is what your preparation has to target.
The loop falls into three sections, each with its own guiding thread. The first 50 km follow Fjorden Rundt, a permanent cycling route. Up to km 90 a second fixed cycling route, the Vestkystruten, takes over. Only then do you leave that framework: over the final ten kilometres, wire flags mark the way to the finish.
You will find no climb worth the name on the whole circuit. Just 96 m of ascent is spread over almost 100 km, less than a metre per kilometre. If you know ultras from the mountains, you will miss the familiar alternation of hiking up and rolling down. Nothing in the terrain changes your stride, so the same muscles do the same work from first step to last.
The race takes its character from its geography: a circuit of Ringkøbing Fjord, run on cycling routes rather than mountain paths, with 13 depots along the way. At the end waits Ringkøbing's athletics stadium, where every participant finishes. This is a summer ultra in August, where the distance is measured not against a high pass but against the full span of a trip around the fjord.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|
Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
With no terrain to slow you, the brake has to come from you. On the Fjorden Rundt section choose a pace that feels almost too easy, and fix your walking breaks from the start, because no climb will make that decision for you. The 13 depots divide the loop, on average, into pieces of seven to eight kilometres: they are the natural moment to walk briefly, eat and drink.
The day is decided on the Vestkystruten between km 50 and km 90. By then you have been in one movement pattern for hours, and no descent hands you free kilometres. Anyone still working calmly from depot to depot here passes plenty of runners who spent everything by halfway.
The biggest trap is the low ascent itself: it tempts you to think like a marathon runner and bank time early. On a flat course that buffer gets paid back twice over. Stay mentally sharp from km 90 as well, since guidance switches there from the cycling route to the wire flags, and a wrong turn costs dearly in that state.

Age-group athletes are out here for roughly nine to thirteen hours. The effort is almost entirely steady and aerobic, with no spikes: the race asks for neither climbing strength nor fast legs, only the ability to hold a moderate pace for a very long time without fading.
The critical stretch is the final third, when your legs have repeated the same stride tens of thousands of times. What sets it apart is the monotony: in the mountains, gradient shifts the load from one muscle group to another, whereas here it stays in the same places. So plan long runs on the flattest ground you can find, ideally along a cycling route like the race itself. Hilly forest loops train something else.
The core of your preparation is back-to-back weekend sessions, two long runs on consecutive days, which build tired legs without the recovery cost of one giant run. Add strength work for hips, glutes and calves, because those muscles hold the even stride together when it starts to come apart. Rehearse the mix of running and fixed walking breaks too, so it is routine by race day.
The August date puts your longest sessions in the summer months before it. Use them to learn what and how much you can eat and drink over many hours, and practise the race's rhythm while you do: a short stop every seven to eight kilometres. With 13 depots you need to carry little yourself, but your stomach has to know that cadence.

Ringkøbing Fjord Summer Edition is 100 km long. That distance shapes how much aerobic endurance, pace durability, and race-specific work belong in the training plan.
Ringkøbing Fjord Summer Edition has around 96 m of elevation gain over 100 km. That affects pacing, muscular load, and preparation for late-race sections.
Ringkøbing Fjord Summer Edition is classified as Flat, averaging 1 vertical metres per kilometre. 99% of the route is flat, 1% climbs moderately (2 to 6%) and 0% is steeper than 6%.
