Race briefing
160K course165 km · 4740 m gain
The station table gives 165 km with 4740 m of climbing, 29 m per km. By leg totals, roughly 42% of the gain sits in the first half.
The steepest leg runs KERAMET to MAHMUDİYE: 8.8 km for 568 m, 65 m per km, 123% above the course average. This is hiking terrain. Walking it costs less than the minutes you would burn forcing it.
The last 4.3 km are easy ground with 11 m left to climb. Plan your finishing pace around that.
These are leg totals. The table does not say where inside a leg the climbing sits, so the steep parts of a leg will be harder than its average.
- Sunset is 19:34 and the finish cut-off is 02:00. A runner using the full time allowance spends the final 10 hours 56 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 optional: 29 m of gain per km. Bring them to protect your legs, not to gain speed.
The course flow is read from the aid station table published by the organiser; without a GPX file there is no kilometre by kilometre grade profile.

- Poles are strongly recommended for this profile. The table gives 31 m of gain per km and the heaviest leg runs at 62 m per km. If you have trained with them and the organiser allows them, they can help share the load on the climbs.

The station table gives 49 km with 1559 m of climbing, 32 m per km. By leg totals, roughly 73% of the gain sits in the first half.

The steepest leg runs MÜŞKÜLE to MÜŞKÜLE: 2.5 km for 200 m, 80 m per km, 150% above the course average. This is hiking terrain. Walking it costs less than the minutes you would burn forcing it.
The last 3.9 km are easy ground with 11 m left to climb. Plan your finishing pace around that.

- Sunset is 19:35 and the finish cut-off is 23:00. A runner using the full time allowance spends the final 3 hours 25 minutes in darkness.

- 73% of the climbing is in the first half. Start easy; less climbing later does not remove the cost of the descents and accumulated fatigue.

25K course25 km · 358 m gain
The station table gives 25 km with 358 m of climbing, 15 m per km. By leg totals, roughly 55% of the gain sits in the first half.
Leg by leg: the first 3.9 km for 48 m (DERBENT), the next 17 km for 299 m (ÇAMDİBİ), the last 3.9 km for 11 m (IZNIK).
The steepest leg runs DERBENT to ÇAMDİBİ: 17 km for 299 m, 18 m per km. A gentle gradient: this is the leg where the time comes back.
The last 3.9 km are easy ground with 11 m left to climb. Plan your finishing pace around that.
These are leg totals. The table does not say where inside a leg the climbing sits, so the steep parts of a leg will be harder than its average.
- Even at cut-off pace you finish 5 hours 36 minutes before sunset. This one is run entirely in daylight.
- The table does not show a clear need for poles: 15 m of gain per km. If you are not used to them, running with your hands free may be more comfortable.
The course flow is read from the aid station table published by the organiser; without a GPX file there is no kilometre by kilometre grade profile.

Key decision points
DERBENTkm 3.9
- The heaviest leg is next: 17 km with 299 m of climbing.
- The longest unsupported stretch starts here: 17 km. Leave with full capacity.
- Cut-off: 0h 50m after the start.
- The longest stretch between official aid stations runs from DERBENT (km 4) to ÇAMDİBİ (km 21): 17 km, with 299 m of climbing in between. Top up at DERBENT and size what you carry to the expected duration and your own drinking rate.
- Drinks only, no food, at ÇAMDİBİ (km 21). Loosen the flask caps on approach; with no queue, refill and leave in 20-30 seconds. Carry the food you will need from the previous station.
- The overall cut-off is 5h, 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 DERBENT (km 4) to ÇAMDİBİ (km 21): the official time budget is 3h 10m for 17 km and 299 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

160K: Sunset is 19:34 and the finish cut-off is 02:00. A runner using the full time allowance spends the final 10 hours 56 minutes in darkness.

Check reflective course markers regularly in the dark.

Plan the sleep question before race day: an hour gained on the first night costs two on the second.
