Very hard — by design. The course gains approximately 6,000m (official) over 101km — around 65m per kilometre, placing it in the top 20% most elevation-dense distances in DTR's database. Average uphill gradient is 15.07% (steeper than 95% of the database) and average downhill gradient is 16.32% — one of the 25 steepest descending averages in the database. Over 12km of the course climbs at greater than 20% gradient. The race starts at 20:00, so the early hours are in darkness on exposed high terrain.
The 101km starts at 20:00 on September 3, 2026 from Salvan in the Trient Valley. This means runners spend the first several hours in darkness on exposed high terrain before dawn. A headlamp and appropriate night-running kit are required.
If you're fit and want to stay in the Alps — it's purpose-built for this. SwissPeaks always takes place the week after UTMB, making it a natural extension for runners already in Chamonix. The terrain is comparable in difficulty to UTMB itself; this is not a recovery run. It finishes on Lake Geneva — a very different end-point that adds its own appeal.
Entry is 189 CHF — approximately €2.04 per kilometre at current exchange rates. The SPTiming registration platform may add administrative or platform fees on top of the listed price, so check the final total at checkout. A 5 CHF train ticket to the start in Salvan is available when registering or up to one month before the race.
The SwissPeaks village and race finish is at Bouveret on Lake Geneva in western Valais. The nearest major airports are Geneva (GVA), approximately 2.5 to 3.5 hours from Bouveret, and Zürich (ZRH), approximately 3 to 4.5 hours. The race start is in Val d'Illiez, reachable by train via Monthey and the Mont-Blanc Express line — the 5 CHF race organisation train is the recommended option. Accommodation in the Valais/Bouveret/Monthey area fills early during the SwissPeaks festival weekend. The official site recommends the hotel at the Grande Dixence dam for altitude acclimatisation. Given the 05h00 start time, accommodation near Val d'Illiez the night before is strongly advisable.
