The first 5 km drop 73 m. Fresh legs make it feel free, but you climb every metre of it back.

The longest drag runs from km 21 to km 34: net 841 m over 13 km at 7% average, its steepest roughly 250 m section averaging 18%, 1082 m of climbing in total with 241 m given back. Heaviest kilometres: km 33 147 m, km 31 127 m, km 29 112 m, km 28 108 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.

The backbone of the course runs from km 67 to km 76: net 892 m over 8.9 km at 10% average, its steepest roughly 250 m section averaging 34% on the GPX trace, 1291 m of climbing in total with 399 m given back. It tops out at 1981 m. Heaviest kilometres: km 74 239 m, km 70 232 m, km 73 208 m, km 69 166 m. By the time you start it, about 54% of the day's climbing is behind you. Running is off the table only in the steepest roughly 250 m core; hike that part with short steps and run again once the grade eases.

The longest descent starts at km 89 and loses 1112 m by km 107 at 6% average, its steepest roughly 250 m section averaging 32% on the GPX trace. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it. The drop at km 34 averages 29% over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.

The last 6 km climb 178 m and then drop 274 m. Walk the climb, take the descent back, and hold the sprint until the drop is done.

The leg from Bohinjska Bela to Bled is long and unsupported: 19 km and 1139 m of climbing with no aid in between, so leave Bohinjska Bela with full capacity.

You reach the climb after Bled with about 1156 m of descent already in your quads; treat its first half as recovery effort.

You reach the climb after Dom pri izviru Završnice with about 449 m of descent already in your quads; treat its first half as recovery effort.

You reach the climb after Dovje with about 1488 m of descent already in your quads; treat its first half as recovery effort.

The organiser lists 122 km; the published GPX measures 121 km. The organiser lists 5855 m of climbing; the published GPX measures 6545 m. The technical course notes use the published GPX measurement.
This course reaches 2166 m. A separate forecast for the high-point coordinate gives 3°C to 11°C, wind up to 4 km/h (calm). It is a daily forecast for that coordinate, so arrival time can still change what you encounter.
Sunset is 19:08 and the finish cut-off is 05:00. A runner using the full time allowance spends the final 9 hours 44 minutes in darkness.
Get the headtorch out before sunset and keep spare batteries or a power bank dry and immediately accessible. A spare buried at the bottom of the pack is not an emergency spare.
Check reflective course markers regularly in the dark. If the markings disappear, stop moving forward, return to the last marker and confirm the route against the GPX or organiser app.
At cut-off pace you run into a second night. Plan the sleep question before race day: an hour gained on the first night costs two on the second.
Poles are strongly recommended for this profile. The course averages 54 m of gain per km and the longest climb averaging over 5% runs 13 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
13% of the course is steep descent. Increase your cadence instead of braking, or your quads go early.
The high point is 2166 m. Coming from sea level, your heart rate and breathing shift at the same pace, so leave yourself room in the first hour.
The altitude is not a single summit: about 6.5 km of the course sits above 1800 m. The longest unbroken stretch up high is 6.6 km and the high zone spans roughly km 72 to km 79.
Point to point: the finish sits 34 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.

Course-profile notes are generated from GPX grade data; terrain, rules, aid stations and weather are added only when separately sourced.

The longest stretch between official aid stations runs from Bohinjska Bela (km 25) to Bled (km 44): 19 km, with 1044 m of climbing in between. Top up at Bohinjska Bela and size what you carry to the expected duration and your own drinking rate.
Hot food is served at Žirovnica (km 57). If your stomach and race plan call for it, make this a deliberate 3-5 minute stop; do not sit down simply because hot food is available. Restart gently and let your stomach settle before lifting the effort.
Food is available at Talež Hunting Lodge (km 9) and Kupljenik (km 18) and 7 more. Decide what you need before reaching the table; without a planned special task, collect food and fluids and leave within 60-90 seconds. Finish eating on the next calm, suitable section.
Drop bag at Žirovnica (km 57). Write down the equipment and food you expect to replace before the race so the decision is already made when you arrive.
Crew support is permitted only at Bohinjska Bela (km 25), Bled (km 44), Žirovnica (km 57), Dovje (km 104), Gozd Martuljek (km 115), and Kranjska Gora (km 122). This is not the same as a drop bag: plan equipment and food hand-offs around these stations, then verify wristband, bag and transport rules with the organiser.
The last aid station is Gozd Martuljek (km 115), leaving 7 km to the finish. After that you are on what you carry.
The heaviest leg runs from Žirovnica (km 57) to Dom pri izviru Završnice (km 70): 13 km with 1218 m of climbing. Treat it as the slowest part of your day and get your food out before it.
Medical support is available at Radovljica (km 0), Kupljenik (km 18), Bohinjska Bela (km 25), Bled (km 44), Žirovnica (km 57), Dom pri izviru Završnice (km 70), Prešernova koča na Stolu (km 75), Sedlo Suha (km 87), Dovje (km 104), Gozd Martuljek (km 115), and Kranjska Gora (km 122). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
The climbing starts the moment you leave Sedlo Suha (km 87): the steepest roughly 250 m section averages 32%. Choose food you know you digest easily and fill the bottles, then begin the climb under control.
The overall cut-off is 32h, including all checkpoint stops. Build the plan around the official leg budgets below, not a flat-course average pace.
Relative to distance and climbing, the tightest official time budget runs from Bohinjska Bela (km 25) to Bled (km 44): the official time budget is 4h 30m for 19 km and 1139 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

The race climbs from the gun: 114 m over the first 5 km. Do not chase the crowd, the two minutes you win here get taken back with interest.

The longest drag runs from km 12 to km 22: net 723 m over 9.9 km at 7% average, its steepest roughly 250 m section averaging 28%, 931 m of climbing in total with 208 m given back. Heaviest kilometres: km 19 231 m, km 20 176 m, km 18 162 m, km 15 95 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.

It tops out at 1986 m. Heaviest kilometres: km 31 269 m, km 28 212 m, km 26 192 m, km 30 186 m. Running is off the table only in the steepest roughly 250 m core; hike that part with short steps and run again once the grade eases.

It tops out at 1809 m. Kilometre by kilometre: km 43 61 m, km 44 126 m, km 45 203 m, km 46 86 m. The hard core of this climb is hiking ground; keep the rest at a steady effort and do not fight the wall when it arrives.

The longest descent starts at km 46 and loses 1127 m by km 64 at 6% average, its steepest roughly 250 m section averaging 36% on the GPX trace. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it.

The longest stretch between official aid stations runs from Sedlo Suha (km 20) to Dovje (km 37): 17 km, with 681 m of climbing in between. Top up at Sedlo Suha and size what you carry to the expected duration and your own drinking rate.
Food is available at Valvasorjev dom pod Stolom (km 5) and Sedlo Suha (km 20) and 2 more. Decide what you need before reaching the table; without a planned special task, collect food and fluids and leave within 60-90 seconds. Finish eating on the next calm, suitable section.
Crew support is permitted only at Dovje (km 37), Gozd Martuljek (km 47), and Kranjska Gora (km 55). This is not the same as a drop bag: plan equipment and food hand-offs around these stations, then verify wristband, bag and transport rules with the organiser.
The last aid station is Gozd Martuljek (km 47), leaving 8 km to the finish. After that you are on what you carry.
The heaviest leg runs from Valvasorjev dom pod Stolom (km 5) to Sedlo Suha (km 20): 15 km with 962 m of climbing. Treat it as the slowest part of your day and get your food out before it.
Medical support is available at Jezero Završnica (km 0), Sedlo Suha (km 20), Dovje (km 37), Gozd Martuljek (km 47), and Kranjska Gora (km 55). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
The climbing starts the moment you leave Sedlo Suha (km 20): the steepest roughly 250 m section averages 33%. Choose food you know you digest easily and fill the bottles, then begin the climb under control.
The overall cut-off is 15h, including all checkpoint stops. Build the plan around the official leg budgets below, not a flat-course average pace.
Relative to distance and climbing, the tightest official time budget runs from Dovje (km 37) to Kranjska Gora (km 55): the official time budget is 4h for 18 km and 715 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

The published GPX measures 24 km with 1290 m of climbing, 53 m per km. The course sits between 740 m and 1086 m of altitude. 52% of the gain sits in the first half.

0-9.9 km · Start → Gozd Martuljek: 376 m up / 426 m down; the stretch keeps rolling.

21-24 km · Podkoren → Finish: 207 m up / 288 m down; the stretch keeps rolling.

The first 1.9 km are close to flat, good for settling in. Do not set your pace here, the real course starts after.

The climb between km 1 and km 5: net 205 m over 4.3 km at 5% average, its steepest roughly 250 m section averaging 14%, 290 m of climbing in total with 85 m given back. Kilometre by kilometre: km 2 38 m, km 3 110 m, km 4 41 m, km 5 91 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.

The backbone of the course runs from km 9 to km 13: net 318 m over 4.6 km at 7% average, its steepest roughly 250 m section averaging 22%, 409 m of climbing in total with 91 m given back. Kilometre by kilometre: km 10 24 m, km 11 168 m, km 12 110 m, km 13 72 m. Trying to run this costs far more than it saves. Shorten the stride, lean on the poles, keep moving.

The steepest wall stands between km 17 and km 22: net 287 m over 4.4 km at 6% average, its steepest roughly 250 m section averaging 30%, 370 m of climbing in total with 83 m given back. Kilometre by kilometre: km 18 63 m, km 19 54 m, km 21 83 m, km 22 164 m. By the time you start it, about 70% of the day's climbing is behind you. At this point in the day most runners walk this gradient. Settle into a hiking rhythm and let the metres come.

The longest descent starts at km 5 and loses 269 m by km 9 at 7% average, its steepest roughly 250 m section averaging 16%. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it. The drop at km 13 averages 24% over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.

The last 2.9 km climb 85 m and then drop 288 m. Walk the climb, take the descent back, and hold the sprint until the drop is done.

The leg from Gozd Martuljek to Podkoren is long and unsupported: 11 km and 705 m of climbing with no aid in between, so leave Gozd Martuljek with full capacity.

The organiser lists 25 km; the published GPX measures 24.2 km. The organiser lists 1090 m of climbing; the published GPX measures 1290 m. The technical course notes use the published GPX measurement.
Even at cut-off pace you finish 4 hours 55 minutes before sunset. This one is run entirely in daylight.
Poles are strongly recommended for this profile. The course averages 53 m of gain per km and the longest climb averaging over 5% runs 4.6 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
19% of the course is steep descent. Increase your cadence instead of braking, or your quads go early.
