The shortest distance at the Snow Trail Arosa is a loop of just under six kilometres that is almost never level. Two climbs take you to a little over 1,900 metres, and the way back runs downhill for three kilometres. For a first January race on snow it is short, but it keeps you working from the gun to the line.
Start and finish share one spot at about 1,740 metres. Straight from the start the course climbs for 700 metres at a little over eight percent, then eases into a short, almost level stretch. The real climb begins at kilometre 1.7: just under one and a half kilometres at a similar gradient, with pitches up to 13 percent. It tops out at the loop's high point shortly after kilometre 3.
From there the second half runs downhill almost all the way, broken only by a small rise before kilometre 5. About half of the whole course is descent and there is practically no flat ground. That makes the loop short but not fast, because your legs keep switching between pushing and braking.
The race is held in early January in Arosa, and even the start sits higher than most hills in lowland Europe. At this altitude every climb costs more breath than at home, however short it is. Underfoot, as the name promises, you have snow instead of forest floor, which turns the way back into a test of footing.
| Start | Length | Ø | Max. | Gain | Cat. |
|---|---|---|---|---|---|
| km 0.1 | 0.7 km | 8.4 % | 13.5 % | +59 m | — |
| km 1.7 | 1.4 km | 8.5 % | 12.9 % | +121 m | Cat. 4 |
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.
Almost all of the climbing on these six kilometres sits in the first half. Take the opening rise calmly even if the field is pushing: after 700 metres you get only a brief respite before the longer climb begins.
That second climb to the high point decides the race. Run it with steady breathing and short steps and you can use the three kilometres of descent that follow. Arrive at the top already in the red and you will lose time downhill, because on snow you can only run fast with some tension left in your legs.
The trap is the short distance itself. Six kilometres invite the pace of a flat 5K, but above 1,700 metres a fast first kilometre comes back to bite you on the main climb at the latest.

Depending on your level you will be out for roughly 30 minutes to an hour. The effort sits close to threshold: two climbs that drive your heart rate up and a return leg where your thighs work harder than your lungs.
What counts is holding a hard, even pace uphill. Train it with hill repeats of three to six minutes on gradients around eight percent, the pitch of both climbs here. A tempo run over rolling ground adds practice at the constant switch between climbing and descending.
Going down takes trust in your footing. Run descents at a brisk pace in training, with short quick steps, and on snow or frozen ground where you can, so your ankles and core know the stabilising work. Strength exercises for calves and hips make those steps steadier.
Arosa in January means altitude and winter. If you can, travel up the day before so you are not racing straight out of the valley. Test shoes with a grippy tread and layered clothing on cold training runs rather than experimenting on race day.
