Iron Bike Race Einsiedeln: Course, Elevation & Route Profile

Course & Elevation

The start is on the Klosterplatz right in front of Einsiedeln Abbey, and the race begins in earnest from metre zero: the opening climb runs 2.6 km at 6.7 percent on average with ramps up to 17 percent. From there the big lap crosses the raised bog near Rothenthurm, climbs the Chatzenstrick and drops into the Alpthal, where the high point sits at roughly 1,340 metres. The hardest climb of the lap starts at km 21.6, lasts 2.6 km and averages eleven percent, with pitches close to 19 percent.

At km 48.5 you roll through the finish arch on the Klosterplatz without stopping and begin the small lap. From there the pattern repeats in shortened form: the opening climb again from km 48.3, the eleven percent ramp again at km 62.9, the nine percent final climb at km 69.8. The last ten kilometres over Friherrenberg and Eselweid then fall back towards the abbey.

The riding is on forest roads, gravel tracks and trail sections through the country between Einsiedeln, Rothenthurm and Alpthal, with Lake Sihl behind you and the abbey village as the finish. 2026 is the 30th edition and also the season finale of the Bike Marathon Classics, so the front of the field is unusually deep. Parts of the route cross cattle pasture and paths that are not public rights of way, and are only opened about a week before race day, which makes course knowledge worth far less here than at most marathons.

Pacing Strategy

The course gives you almost no recovery: only around ten percent of it is flat, 17 percent is steep uphill and nearly 19 percent steep downhill. Your power profile is therefore a constant up and down rather than one long steady climb. The opening climb from metre zero arrives cold and in a full field, and that is where the race is most easily lost. Ride those first 2.6 km clearly below what the group's slipstream would allow.

The long category is not decided on the big lap but on the second passage: if you cross the line at km 48.5 already empty, you still have 32 km and over 1,100 metres of climbing ahead. The eleven percent climb at km 62.9 is where the times fan out, and the nine percent climb at km 69.8 follows with no recovery in between.

The second trap is the descending. Almost a fifth of the route is steep downhill, partly on loose gravel and partly on trail. Braking late with tired hands there costs more than the climb gains, and dragging the brakes all the way down means starting the second lap with them overheated. Plan your drinking and eating deliberately for the flat bog sections around Rothenthurm, because you will not manage either reliably on the steep parts.

Training plan for Iron Bike Race Einsiedeln: 12-week build

For an age-group rider this distance means four to six hours in the saddle, and more at the back of the field. The demand is strongly interval-like: eight climbs of between two and three kilometres, separated by technical descents and only short flat stretches. You are not holding threshold for hours, you are accumulating hard ten to twenty minute blocks across 80 km with incomplete recovery in between.

The second lap decides the race, and that is exactly what training can rehearse. Long rides with the climbing deliberately back-loaded beat evenly distributed endurance rides here: four to five hours with the heaviest climbing in the final hour prepares you for the ramp at km 62.9 far better.

The course also demands handling under fatigue. Nearly a fifth of it is steep descending on gravel and trail, so practise descents at the end of a long session rather than fresh at the start. Alternating seated and standing climbing belongs in the plan too, because ramps up to 19 percent force you out of the saddle while loose ground punishes exactly that.

Late September around Einsiedeln, between 900 and 1,350 metres, is cool and often wet, and the gun goes at eight in the morning. Train in the damp, and plan clothing and tyre pressure for a soft surface. Because the full course is only opened shortly before race day, recon is limited, so build your feeding plan on the organiser's split table rather than on personal course knowledge.
