The Start/Finish point will be located in front of the Municipal building of Tryavna. The courses are looped, meaning all participants start and finish at the same location.

Race Numbers and Chips

Each participant in the event will receive a race number in a polyethylene transparent bag, along with safety pins for attaching it. Along with the race number, they will also receive two chips – one personal and one duplicate – “official” chip.
Race numbers with chips will be distributed in advance in Tryavna the day before the event, according to the event’s schedule.

Rules for attaching race numbers and chips:

– The race number must be attached in a VISIBLE place for runners – on the front of the t-shirt, jacket, or other clothing, oriented upward to be readable from a distance, or on the frame of the bike for MTB distances.

– The chips should not be attached directly to the body (closer than 0.5 cm), as the human body affects high-frequency waves and the chip will not function properly.

Volunteers will instruct all participants on-site and check for proper chip attachment, but remember – your results depend on whether your chip is attached correctly!

All participants who have received their race number and chip set in advance must bring them on the day of the event! If you do not bring your race number and chips, your results cannot be recorded.

The results of the event will be processed and published within the necessary technical time after the event (1-7 days) on the event website – www.tryavna-ultra.com. The organizers are not responsible for technical errors, missing data in the rankings, etc. – according to the general terms and conditions of participation.

Food and hydration stations will be provided, offering carbohydrate-rich food and water to prevent hypoglycemia and dehydration. Where possible, additional volunteers will be placed along the route to assist and guide participants.
