Bosnia and Herzegovina isn’t a destination you can slot into any holiday week. Many of the best off-road routes run through the highlands, and up there altitude, snow and rain decide whether gravel tracks are a joy or a mud bath.
The short answer: for enduro riding in the highlands, June to September is ideal. Read on for why, how spring, summer and autumn compare, and when our groups are out riding.
Altitude sets the season
Kupres, the base of the Bosnia Marathon, sits at around 1,200 metres, with the Kupreško polje plateau just below. It’s one of the highest towns in the country – and a winter sports resort: Hotel Adria Ski stands in the Čajuša ski area.
That tells you most of what you need to know. When skiers are on the slopes, the mountain tracks are not in enduro season. Even once the snow has gone, tracks at altitude need time to dry out. And even in high summer, mornings on the plateau are noticeably cooler than down in the valleys or on the coast.
Spring, summer and autumn compared
Spring: the season starts earlier at lower altitudes and everything is green. In the highlands, though, there’s often still snow, or tracks are wet and heavy after the melt. For off-road routes above 1,000 metres, spring is a gamble.
Early summer: the longest days, tracks that have usually dried out and a plateau that’s still green. The ideal combination for long gravel stages.
High summer: reliable riding, but valleys and the coast can get hot and dry tracks are dusty. Start early and drink plenty.
Late summer and September: the worst of the heat has passed and the landscape turns golden, but the days get shorter. Plenty of riders love this window.
Late autumn and winter: cold mornings, short days and snow in the mountains – not the time for highland off-road touring.
After rain: mud and slippery rock
Whatever the month, heavy rain changes the routes noticeably. Earthy forest tracks turn greasy, karst rock and smooth stones lose grip, and stream crossings carry more water. Yesterday’s fast gravel road can become a genuine challenge.
That’s why the Bosnia Marathon offers a daily choice between the longer, technical Rally route and the easier Classic route, and individual sections can be bypassed on tarmac. Knobbly tyres and a rain suit belong on the trip in every season – the rest is in our packing list.
Why the Bosnia Marathon runs in June
Bosnia Marathon 2027 runs from 12 to 19 June, with six riding days from 13 to 18 June. In mid-June the days are long, the tracks are usually dry and the plateau is green – exactly what you want for around 1,500 km with roughly 70% off-road.
Then there’s the variety of the stages: from Kupres you ride to Bihać, to Sarajevo and down to Neum on the Adriatic. In a single day you can go from the cool highlands to the warm sea, so pack layers rather than one heavy jacket.
Worth knowing when you plan: you don’t return to Kupres every evening. On each of the three two-day stages you spend one night at the destination – Bihać, Sarajevo and Neum – and ride back to the base on a new route the next day. Your main luggage stays in Kupres; what you need for one night travels on the bike.
