EcoTrail Stockholm Winter.
The shortest distance at the EcoTrail Stockholm Winter leaves Stora Skuggan along the water towards Stocksund and Ålkistan, then comes back over Lappkärrsberget. It sounds like a brief outing on snowy winter trails, but the return settles it: the one sustained climb arrives late enough that a misjudged effort there cannot be repaired before the finish.
EcoTrail Stockholm Winter 2027: Course, Route Profile & Map
Start and finish share one spot at Stora Skuggan, and the race is a closed loop. The first part follows the water towards Stocksund and Ålkistan. It stays low without ever settling: a few metres up, a few metres down, again and again, with only about a fifth of the distance properly flat.
The way back runs over Lappkärrsberget and Stora Skuggan, and at kilometre 3.9 comes the section that defines this loop: about 450 metres averaging a little over eight percent, peaking near 15 percent. That puts the water station at kilometre 4 right at the start of the rise. Beyond the top the course drops again and small undulations carry you home to Stora Skuggan.
Nine tenths of the loop run on trails and tracks, the rest on paths and roads, in what the organiser describes as 100 percent nature and snowy winter trails. The event is in its second edition and gives a field of 400 participants, so even the short distance is unlikely to be a solitary run.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 3.9 | 0.5 km | 8.4 % | 14.9 % | +38 m | — |
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.
How to pace EcoTrail Stockholm Winter.
Start under control
The nearly four kilometres before the climb invite you to press, because the course stays low and looks harmless. In fact much of the climbing is already hidden here in a long run of small undulations. Run this part by feel rather than by the watch: on snow, pace says little about effort.
Hold your rhythm
The race is decided between kilometres 3.9 and 4.4. Forcing the steepest metres on snow costs more than it returns. Shorten your stride and walk a brief stretch if you must, rather than reaching the top with nothing left in your legs.
Spend what is left
The trap is the timing of the water station: stop at kilometre 4 and you lose your momentum exactly where the climb needs it. This distance is short enough to run past it. The last kilometre and a half falls first and then only undulates gently, and with some breath saved you gain more time there than on the hill itself.
Training plan for EcoTrail Stockholm Winter: 12-week build
Build the base
Age-group runners will be out for roughly 35 to 55 minutes. The effort is high throughout, but it is no steady threshold race like six kilometres on the road: the constant undulations break your rhythm, and the climb at kilometre 3.9 puts a clear anaerobic spike into the last third.
Train race pace
Train exactly that order: nearly four kilometres at a brisk pace, a steep climb of two to three minutes, and straight back into running at the top. Add hill intervals of that length to the end of a hilly steady run, and pay attention each time to the first 200 metres past the crest, because that is where you find out whether the closing stretch is still runnable.
Rehearse the course
The January date shapes the preparation too. On a snowy surface, drive comes from short steps and stable ankles rather than a long push-off. Move part of your running onto trails once snow is lying there, and test race-day shoes on exactly that ground, not for the first time at the start.
Arrive fresh
If you mostly run on tarmac, switch to trails regularly in the final weeks before 30 January, since nine tenths of the race happens there. Include short descents as well: running downhill relaxed on slippery ground saves strength for the final stretch that others will be missing.
