To mark the milestone NLB 30th Ljubljana Marathon, Slovenian brand LELOSI presents its new Marathon Collection, created for everyone who knows that running is not just about the distance, but about a feeling that stays with you long after you cross the finish line.
As a Diamond Sponsor and the Official Fashion Outfitter of the marathon, LELOSI is gifting runners the official running t-shirt for the third consecutive year. This year, it will once again provide official t-shirts to thousands of participants, becoming part of their preparations, anticipation and memories of the day when Ljubljana runs as one once again.
The official NLB 30th Ljubljana Marathon t-shirt is designed for running: it is lightweight, breathable and soft against the skin, providing runners with comfort from the starting line to the final metres of the course. Its vibrant design, featuring the colours of the event’s visual identity, is inspired by running routes intertwining with the streets of Ljubljana. It is a tribute to the city that transforms into one large running venue every autumn, and to all the stories that begin, continue or reach their ultimate goal on its streets.

A collection for every kilometre before the big day
The official t-shirt is complemented by the Marathon Collection, designed to accompany runners on their journey to the starting line. It is intended for everyone who has made running part of their everyday life – whether they are training for their first race, chasing a personal best or simply running because they feel better after every kilometre.
Every piece combines freedom of movement, comfort and the functionality runners need from their first training session to the final metres before the finish line. Because sometimes we run for a result, sometimes for a clearer mind, but always for the feeling that we are capable of more than we thought.
Discover the Marathon Collection
One of this year’s highlights is the women’s running windbreaker. This lightweight layer provides protection from the wind without restricting movement and is easy to take along when the forecast is unpredictable. It is made for days when the weather does not cooperate, but your determination remains strong.

Leggings for every running pace
The women’s leggings featuring the NLB 30th Ljubljana Marathon design are made from soft and stretchy LeloSkin material, which adapts to the body and allows unrestricted movement. Two practical pockets keep your essentials close at hand while you run.
For runners who prefer a more understated look, the collection also includes solid-colour nylon leggings. The smooth and stretchy material comfortably hugs the body and follows every movement, whether during fast training sessions or over longer distances. On warmer days, they can be replaced with running shorts designed for a light, effortless stride even as temperatures rise.

The men’s sports leggings are made from stretchy nylon and feature breathable mesh detailing to help release excess heat. Zips at the back of the legs make them easier to put on and adjust, while the close-fitting cut allows unrestricted movement even at a faster pace.

For cold mornings and final preparations
The collection is completed by arm warmers and a headband for colder mornings, evening training sessions and days when you need an extra layer before the start. A unisex hoodie will also be joining the collection soon, perfect for warming up, travelling to training and unwinding after the final kilometre.

For a city that runs
For three decades, the Ljubljana Marathon has brought together experienced marathon runners, recreational runners, supporters and everyone who believes in the power of movement. The Marathon Collection is a tribute to this community – to the perseverance, energy and courage that fill the streets of Ljubljana every year.
LELOSI continues a partnership that goes far beyond simply being present along the course. With the official t-shirt, the brand will once again become part of thousands of running stories – from the first preparations and demanding training sessions to the moment when effort turns into pride.
For a city that runs. For people who persevere. For every step towards the finish line.
