Race guide
Updated 19 July 2026
The Vaarojen Maraton 43 km is the grand finale of the Trail Tour Finland series, staged in the rugged Koli National Park in North Karelia. Covering 43 kilometres with 1,114 metres of cumulative elevation gain, the course loops through the forested vaara (hill) terrain that defines this corner of eastern Finland, starting and finishing at Koli at around 295–298 metres above sea level. With a high point of 332 metres the individual rises are modest in absolute terms, but the relentless undulating nature of the terrain – characteristic of the ancient worn-down Karelian uplands – means the climbing never fully lets up and accumulates into a genuinely demanding day on the trails. As the closing race of the Trail Tour Finland series, the event carries extra weight for runners chasing series standings, making both competitive execution and reliable finishing especially important. Two water stations at Kiviniemi (17 km) and Peiponpelto (32 km), plus crew access at start and finish in Koli, give a straightforward support structure over what is a largely self-reliant course.
Course & Terrain
The route begins and ends in Koli, a well-known fell and national park area whose trails wind through dense boreal forest, across rocky ridgelines and through the mossy, rooted paths typical of Finnish vaara landscape. The course drops from the Koli start down towards Kiviniemi at 102 metres by the 17 km mark – a net descent of nearly 200 metres that masks significant up-and-down movement across the ridges along the way. The middle section rises back through the forest to Peiponpelto at 131 metres at 32 km before the final 11-kilometre push climbs back up to the finish at 295 metres. Expect trail surfaces that mix rocky singletrack, rooted forest paths and softer sections through boggy low-lying ground. The terrain rewards runners who are comfortable on technical footing – loose rocks and tree roots are ever-present – and those accustomed to reading trail rather than running on smooth paths will gain meaningful time. Trekking poles are a personal call, but the repeated short ascents and descents make them a reasonable option for runners who train with them.
The Decisive Climbs & Where the Race Is Won or Lost
Despite a maximum elevation of just 332 metres, the 1,114 metres of total ascent spread across 43 kilometres means an average of roughly 26 metres of climbing per kilometre – a persistently hilly profile. The most consequential stretch is the final 11 kilometres from Peiponpelto back up to Koli, which demands a sustained climb back to 295 metres when the legs are already deep into fatigue. Runners who have gone out too hard or under-fuelled in the middle section will suffer here; those who have managed effort sensibly will be able to push through the forest finish. The early descent towards Kiviniemi can feel inviting and fast, but this is precisely where the race is frequently lost. Bombing the downhills in the first half burns out the quads and leaves little in reserve for the closing climb. Keep something back on every descent – the terrain will take it from you on the way back up if you don't.
How to Pace & Fuel the Race
With two water stations at 17 km (Kiviniemi) and 32 km (Peiponpelto), the longest unsupported stretches are the opening 17 km and the closing 11 km back to Koli. Carry enough fluid and calories to cover 17 kilometres comfortably from the start, and reload properly at both stations. The Peiponpelto stop at 32 km is especially important: top up fluids and take on calories here because the final climb to the finish is the hardest section on already-tired legs. A conservative approach in the first third pays dividends. Treat the opening kilometres out of Koli as a warm-up, resist racing the descent towards Kiviniemi, and aim to feel controlled and well within yourself through the midpoint. Once through Peiponpelto at 32 km with energy still in the tank, you can open up on the final push. The finish cut-off is midnight on Saturday night (Sunday 00:00), giving a generous window, but the Kiviniemi cut-off at 17:00 on Saturday keeps the early pacing honest – arriving at 17 km behind schedule signals a problem that the demanding second half will only compound.
Conditions to Expect
Koli in the Finnish trail running season means predominantly cool to mild temperatures with a high probability of wet trails. The boreal forest holds moisture well and even a dry spell can leave roots and rocks slick underfoot; after rain the boggy sections become genuinely soft and demanding. Grip-focused trail shoes with a lugged sole are strongly recommended over general-purpose road-trail hybrids. Daylight and temperature will depend on the precise race date within the Trail Tour Finland calendar, but runners should be prepared for conditions to deteriorate toward evening given the midnight cut-off. Carrying a lightweight waterproof layer and a headtorch is prudent regardless of conditions at the start – the closing kilometres may be run in darkness, and forest trails in fading light demand extra care on the technical sections.
