What Makes Transruinaulta Different from Every Other Swiss Trail Race?
Q: How hard is the Transruinaulta 42K? A: Moderate. At 42.7m/km and 22.8% flat terrain, the gradient profile is challenging but not extreme — comparable in elevation density to Les Templiers Grand Trail. The course leans net-descent (40% downhill), rewarding runners who pace the canyon climbs well. The technical character of the gorge trail and sustained gradient mean there are no easy kilometres.
Course Profile — Canyon Singletrack, Wooden Bridges, and a Net Descent to Thusis
Q: Can I combine Transruinaulta with another race? A: Yes. The Transviamala (19km, Thusis-based) runs the following day and can be entered as a two-day stage race with the 42km for CHF 175 total.
€2.45 per Kilometre — What Swiss Canyon Organisation Costs
Q: How much does it cost to enter Transruinaulta 42K? A: CHF 95 standard entry — €2.45 per kilometre — placing it near the premium end of the European trail market for a 42km race. Swiss operational costs and 22 years of race infrastructure are reflected in the price.
