when:
Budapest Sport Office (Budapest Sportiroda, BSI) is back in 2026 with a packed calendar that gets Hungary moving. From lake-spanning open-water swims to glow-lit night runs and the country’s biggest marathons, tens of thousands will chase finish lines, views, and that unbeatable group buzz. Check the dates, pick your challenge, and jump in.
February 26 to March 1 brings the 16th Balaton Supermarathon (Balaton Szupermaraton), a four-day tour of the “Hungarian Sea.” Go solo, pair up, or form teams of 3–4 or 5–8 and circle the lake in a rolling festival of endurance and scenery. Want a taste without the ultra label? Marathon+ (Maraton+) lets you join the supermarathoners for a single day and complete the day’s full distance on your own. Base city: Siófok, 8600.
On February 27, line up for a rare weekday race: a half marathon along the shore from Keszthely to Szigliget. Yes, it’s Friday—clear your home office yourself, then let BSI handle the rest. Twenty-one kilometers of early spring Balaton vibes, start in 8360 Keszthely.
Marathonfüred (Maratonfüred) hits on February 28 with a marathon-distance shot of spring. If ultras don’t call yet, kick off the season with 26.2 miles along the lakeside route. Expect near-perfect running weather and winter-waking views of the water. Host area: Badacsony–Badacsonytomaj, 8258.
February 28 to March 1, the HalfBalaton Supermarathon (FélBalaton Szupermaraton) serves up 94.8 kilometers over two days—solo, in pairs, or with teams of 3 or 5–8. You can split daily legs however you like, so a three-person relay can wrap it with roughly 9–12 miles each per day. Same stunning lakeside payoff, fewer miles at once. Badacsony–Badacsonytomaj, 8258.
On March 1, chase a half marathon along the celebrated high bank: start in Balatonakarattya and run into the Day 4 finish in Siófok. Parts of the course hug the lake, with that late-winter, early-spring shimmer as your pacer.
Budapest lights up March 21–22 with the city’s spring classic based on Margaret Island, threading past postcard landmarks. It’s for everyone—families, first-timers, and speedsters. Choose:
– March 21: Vivicittá City Tour 9.3 miles; City Tour 5 miles; 3-person relay; Minicittá 1.5 miles; Walking event; Family Run; Midicittá 4.3 miles
