Zagreb is famous for its beautiful city parks, which provide the perfect place for running. One of the most popular is Maksimir Park, a true jewel of greenery in the heart of the city. Established in the 18th century, this sprawling park offers runners more than 316 hectares of scenic grounds. The running trails in Maksimir Park lead through varied terrain, from flat alleys to slightly hilly paths, allowing you to tailor your workout to your preferences. The park is famous for its beautiful lakes, old-growth forest and abundant fauna, making running here a true pleasure for the senses.

Another great place for running is Bundek City Park. This modern city park, located in the southern part of Zagreb, offers runners well-maintained paths around a picturesque lake. The route around the lake is about 1.5 kilometers long, making it ideal for both beginners and advanced runners. Bundek City Park is particularly popular with families with children, thanks to its numerous playgrounds and rest areas.

Also not to be missed is Jarun Park, known as the 'Sea of Zagreb'. This vast recreational complex, located around Jarun Lake, offers runners more than 6 km of running paths. The route around the lake is flat and well-marked, making it ideal for long-distance training. Jarun Park is not only a place for running, but also a center for water sports and recreation, where after a workout one can relax on the beach or enjoy the numerous cafes and restaurants.

Comparing the three parks, each has its own unique advantages. Maksimir Park offers the most diverse terrain and the largest area, ideal for those who like to run in a more natural environment. Bundek City Park is the smallest, but the most family and beginner-friendly for runners. Jarun Park, on the other hand, is distinguished by its trail length and proximity to water, which is especially appreciated on hot days. All three parks are easily accessible by public transportation and offer free admission, making them ideal places for regular workouts for locals and tourists.

For those seeking tougher thrills and more challenging trails, Zagreb offers excellent mountain running opportunities. One of the best-known and best-loved trails is Medvednica Mountain Trail 9. Part of the larger trail system in the Medvednica Mountains, this trail offers runners an unforgettable experience and breathtaking views of the city.

Medvednica Mountain Trail 9 is an approximately 9-kilometer trail that runs from Talan to the Risnjak hut. It features varied terrain, combining gentle climbs with flat sections. The route is well marked and maintained, making it safe even for less experienced mountain runners. Runners praise it for its beautiful views, clean air and the opportunity to escape from the hustle and bustle of the city.

For those looking for an even greater challenge, an excellent option is the Leustekova staza. Named after Albino Leustek, a forestry superintendent who contributed to the development of tourist infrastructure in the Medvednica mountains, this route offers runners a true mountain experience. The route is 6.4 kilometers long and runs from Gračanski dolj to Stara lugarnica near Činovnička livada.

Leustekova staza is characterized by a higher degree of difficulty than Medvednica Mountain Trail 9. The route is steeper and more technically demanding, making it ideal for experienced mountain runners. It does, however, offer incredible views of Zagreb and the surrounding forests, which makes up for the effort put into tackling the more difficult sections.

Comparing the two trails, Medvednica Mountain Trail 9 is more amenable to a wider range of runners, offering a good compromise between challenge and accessibility. It is longer, but less steep, allowing for smoother running. Leustekova staza, on the other hand, is shorter, but more technically and conditionally challenging. Both trails are well-maintained and marked, increasing runner safety.

It is worth noting that both trails are accessible all year round, but in winter they can be slippery and require additional equipment. In summer, on the other hand, they offer pleasant coolness and shelter from the urban heat. For safety, especially on Leustekova staza, it is recommended to run in pairs or small groups.

Running on these mountain trails not only provides an intense workout, but also allows you to enjoy the beauty of Croatian nature and the Zagreb skyline. It's a great way to combine active recreation with exploring the city's surroundings.

When going for a run in Zagreb, it's worth keeping in mind some practical tips that will help you fully enjoy the activity and explore the city safely.

First, Zagreb's climate is characterized by hot summers and cool winters. During the summer, it is recommended to run early in the morning or evening to avoid the heat. Parks such as Maksimir and Jarun offer the shade of trees, which is an added advantage on hot days. In winter, on the other hand, trails in the parks are usually cleared of snow and safe for running.

It is worth noting the availability of amenities on the running trails. Maksimir Park and Jarun Park offer public restrooms, drinking water fountains and rest areas. For mountain trails such as Medvednica Mountain Trail 9 and Leustekova staza, bring your own water and snacks, as amenities there are more limited.

Safety is key, especially for those running solo. City parks are generally safe and well-lit, but for mountain trails it is advisable to run in a group or inform someone of your planned route. It's also a good idea to take a cell phone with you in case of unforeseen situations.

For those who want to combine running with sightseeing, routes in the city center, such as the area around Zrinjevac Park or the promenade along the Sava River, offer the opportunity to see Zagreb's historical sights. These routes are shorter, but allow for a 'running tour' of the city.

In terms of equipment, ordinary running shoes are sufficient in the city parks. However, on mountain trails, especially on Leustekova staza, trail shoes with better grip are recommended.

For those looking for running company, there are several running clubs in Zagreb that organize regular group training sessions. This is a great opportunity to meet local runners and discover new trails.

Running events held in the city are also worth mentioning. The Zagreb Marathon, usually held in October, is the largest running event in the city, offering routes of various distances. It is a great opportunity to experience running in Zagreb in a unique atmosphere.

All in all, Zagreb offers runners exceptional training opportunities in a variety of terrain - from flat city parks to challenging mountain trails. Regardless of your running level, there is something for every runner. Running in Zagreb is not only a form of physical activity, but also a way to get to know the city and its beautiful natural surroundings. When planning your active stay in Croatia's capital, consider these running routes to fully experience the charm of this fascinating city.
