Entries are accepted online only through the official registration system of the Turkish Athletics Federation (TAF). The total quota is 1500 runners and the system closes to new entries as soon as it is full. Entries, course changes and document uploads close on 28 March 2027 at 23:59. Nature park entrance fees are not included in the entry fee.
Mandatory gear list
The list below applies to the 18K and 38K courses. Equipment is checked by marshals; runners with missing items are not given their kit.
A backpack or waist pack to carry the equipment
A water container with a total capacity of at least one litre (bladder, bottle, flask and so on)
Race bib attached visibly to the body
Mobile phone (with the organisation or emergency numbers saved)
Emergency blanket (aluminium)
Whistle
Waterproof jacket
Long-sleeve base layer
Beanie or buff
Cup (no plastic cups will be available at the stations)
Timing chip (provided by the organisation)
No mandatory gear check is carried out for 8K runners beyond the race bib and timing chip. However, as no plastic or paper cups are provided at the checkpoints, runners are advised to carry a collapsible cup or a 500 ml water container (bottle, flask and so on).
The primary stage of the mandatory gear check takes place during kit collection; runners with missing equipment are not given a race bib. The jury and organisation officials have the right to carry out random gear checks at any checkpoint on the course. Missing items lead to a time penalty (+10/30 minutes) or direct disqualification, depending on the scale of the breach. Participants are responsible for collecting their kit before the start time of their race.
Entry requirements and medical documents
Any runner who has turned 18 by 4 April 2027 (born in 2009 or earlier) may take part. The required documents differ per course:
8K and 18K: A wet-signed waiver (participant undertaking) stating that the runner has no condition preventing trail running, a medical report issued within the last year, or an athlete licence in athletics, triathlon, mountaineering or orienteering is sufficient.
38K: A valid medical report issued within the last 6 months bearing the statement "fit for running/athletics", or a currently endorsed athlete licence in athletics, triathlon, mountaineering or orienteering is mandatory. If documents are missing, the participant undertaking alone is not accepted for this course and the runner is not allowed to start.
Age categories and awards
Age is calculated by year of birth based on the year of the race (2027) under TAF standards, regardless of day and month. The classification on all of the 8K, 18K and 38K courses is as follows:
Men's / Women's overall
Men's / Women's under 30
Men's / Women's 30+
Men's / Women's 40+
Men's / Women's 50+
Men's / Women's 60+
No double podium: runners who reach the overall podium (top 3) cannot also take an age-category award even if they place in their category; the next runner in that category is invited to the podium instead.
To be considered for an award or the podium, the race must be completed within the official cut-off times and in accordance with the rules. Categories with insufficient entries may be merged by decision of the jury.
Awards, catering and kit contents
Silivri Ultra Trail is a professional organisation run in an amateur spirit focused entirely on sportsmanship, love of nature and trail culture. No prize money is awarded to runners who place in the rankings.
Every participant who completes the race within the official time limits and in accordance with the rules receives a finisher medal. Runners who place in their category also receive a placement medal and/or trophy.
Regardless of course, all runners receive the official Silivri Ultra Trail commemorative shirt during kit collection.
8K and 18K: a "Finisher Buffet" in the finish area (snacks, fruit, hot and cold drinks).
38K: a hot, restorative "Finisher Meal" in the finish area.
Bag drop
The organisation operates a bag-drop tent in the start area from 06:00 on Sunday 4 April 2027.
Spare bags containing no valuables (phone, cash, wallet and so on) may be handed to marshals with the race bib fixed to them.
The organising committee cannot be held legally responsible for loss, theft or damage to bags left at the bag drop.
Bags must be collected by 15:30 after the award ceremony, on presentation of the race bib.
Emergencies and contact
An organisation emergency line has been set up for serious injury, getting lost or situations requiring urgent medical help during the race: +90 530 642 33 76. This number will be printed in large type on the back or front of every participant's race bib.
A runner who loses their bearings, is injured or needs urgent help must stay put without leaving the trail or forest road, and call this number to report their situation and location.
Mobile signal can be weak in some deep forest and basin areas of Danamandıra Nature Park. Where there is no signal, move towards the nearest open area or hilltop without straying from the route, and blow the emergency whistle from your mandatory gear at intervals to signal to the sweeper or rescue teams.
This page is a summary. The binding provisions are set out in the General Race Rules and in the Participant Undertaking and Waiver.
