Participants speak

  • In 2018, for a second time in a row, I have cycled the whole of Slovenia in one day. It was accompanied with a pleasant company 🙂 During the trip, joy, conversation, coexistence and help count, and not competition or victory. This is a great opportunity to experience great sport pleasures in a beautiful countryside. Organization of the event itself is perfect!

  • I attended Diagonala 335 for a personal challenge, “if I can”. It was great, everything was great, the escort, refreshments and companions. I would recommend that you get for yourself a good head light with a durable battery or 2 lights for approx. 5h operation and get on the road.

  • Different, new, perhaps slightly crazy and unusual experience. Challenge, start at midnight, always available supporting team, enough stops and most of all, fun. I recommend you take the route; it will be an unforgettable experience. You also have an available accompanying vehicle at all times and, of course, and nice people around to support you.

  • I applied for the event with a fear not being able to hold out such a distance. But all the fear was gone just after we started. I had a simple goal to take the distance to Portorose. It was so great that I hardly wait to take a part at the event this year.

  • I attended the Diagonala event mainly because I like cycling and I adore the beauty of our land as well as because of the charity. I really liked everything from the route itself on one side, which was very diverse, to the good company one another side. I have met many nice people and I cannot wait to participate this year again. The feeling was so great.

  • There is a time in the year when soulmates gather in Trdkova (start of Diagonala335) and start cycling into the night. Shining reflectors, strong lights, smiling faces, positive people on the wheels, shortly invaluable. Along the Slovenian diagonal we explored its beautiful places. At the end only the brave ones jump traditionally into the sea. Welcome hopers.

  • I took part at the event with a plan B to stop in Ljubljana, which of course did not come into consideration. I had a few starting problems during the night at first, but after the day break all doubts disappeared. The atmosphere, the help, and everything else was TOP, even the accompanying team was so much supportive. I’m happy to go again. Happy Diagonal!

  • I am still gathering memories of those 14 hours of cycling through beautiful Slovenia. The company was unique. The feeling with a view of the whole route was really unique, something I have not experienced yet. I would advise this experience to anyone who likes challenges, who like cycling and eating Trojan donuts.

  • Diagonala335 was an amazing and empowering experience. I was nervous at the beginning but everyone was so encouraging and supportive. I pushed myself very hard and it felt like such an achievement at the end. I will never forget the exhilaration of coming fast down Črni Kal before the seaside.
