Race guide
Updated 19 July 2026
The NUTS Ylläs Pallas Polkujuoksu is a 161 km point-to-point ultra that traverses the wild fell country of Finnish Lapland, running south from Hetta in Enontekiö to the ski village of Äkäslompolo. With 3821 m of cumulative elevation gain and a high point of 747 m, it is not a mountain race in the Alpine sense — the terrain is arctic tundra, bog, heathland and forest trail, where the relentlessness comes from the sheer distance, the exposure and the unforgiving pace requirements built into the cut-off schedule. It is a race that rewards honest pacing, meticulous crew coordination and a thorough respect for the Lapland environment, not just technical climbing ability. The course passes through the Pallas-Yllästunturi National Park, one of Finland's most iconic wilderness corridors, linking the fells of Pallas at the 66 km mark to those surrounding Ylläs near the finish. Runners have a midnight Sunday cut-off in Äkäslompolo, meaning most of the race unfolds across a single night and the following day — with the middle section from Pallas through Rauhala and Pahtavuoma demanding that runners hold together during the small hours when both body and mind are most vulnerable.
Course & Terrain
From the start in Hetta at 296 m, the course rolls immediately into open fell terrain toward Mustavaara (Pyhäkero) at 11.7 km before dropping to the crew point at Ketomella (31.5 km, 265 m). The early kilometres set the tone: marked trails cross exposed heathland, soft boggy ground and rooted forest paths in quick succession. There is no single brutal climb to point to — instead the elevation is accumulated across dozens of steady fell shoulders, each one modest in isolation but accumulative over 161 km. The high point of 747 m is reached somewhere in the Pallas area around the 66 km mark, after which the terrain opens into a long middle passage through Rauhala, Pahtavuoma and Peurakaltio before the course re-engages with the forested fell slopes approaching Ylläs. The final 21 km from Ylläsjärvi through Kellokas to Äkäslompolo involves further rolling trail through the Ylläs fell complex — do not treat this section as a formality; cut-offs remain tight and the terrain stays technical underfoot.
Decisive Sections — Where the Race Is Won or Lost
The stretch from Hetta to Pallas (66 km) must be run conservatively. Arriving at the Pallas crew point before the Saturday 03:00 cut-off sounds straightforward, but runners who go out too hard on the open fell in the first 30 km often arrive at Ketomella already behind on food and fluid. From Pallas, the race enters its hardest psychological window: the 87 km Rauhala cut-off falls at 08:00 Saturday, meaning runners cover the 21 km from Pallas through the night and into early morning. The gap between Rauhala (08:00) and Pahtavuoma at 98.3 km (10:00) is only two hours for 11.3 km — a section that must be run, not hiked, by anyone with cut-off pressure. Peurakaltio at 111.7 km closes at 13:00, and from there it is 28 km to Ylläsjärvi with a 19:00 deadline. Any significant time lost between Pallas and Peurakaltio is extremely difficult to recover. Runners who manage their effort evenly through the night section typically arrive at Ylläsjärvi with enough buffer to safely walk-run the final push to the finish.
Pacing & Fuelling Strategy
With 161 km and 3821 m of gain, a target moving pace needs to account for both the fell terrain and the mandatory time cushions at each cut-off. Work backwards from the Sunday 00:00 finish cut-off and build a split sheet that gives you at least 45–60 minutes of buffer at Pallas and Rauhala — those two checkpoints are where race withdrawals cluster. Crew points at Hetta, Ketomella, Pallas, Rauhala, Ylläsjärvi, Kellokas and the finish give regular access to drop bags and support; use every one of them actively, not just to check in. Fuelling discipline is non-negotiable: Lapland's open fells are deceptively drying, especially in dry or windy conditions where sweat evaporates instantly and the heat stress feels lower than it actually is. Drink and salt on a fixed schedule regardless of thirst — do not wait for your body to signal. Cognitive fog, stumbling and blankness mid-race are often the first signs of dehydration or heat stress rather than fatigue, and by the time those symptoms are obvious, judgment is already compromised. Brief your crew or a trusted pacer to run an external check on you at each meeting point: are you eating, are you making sense, are your eyes tracking? Their read on you is more reliable than your own when you are deep in the race.
Conditions to Expect
Finnish Lapland races are famous for their variability, and the Ylläs Pallas corridor is no exception. In summer race conditions, daylight is near-continuous this far north, but overnight temperatures on exposed fells can still drop sharply, especially above 500 m. Wind on the open fell tops accelerates heat loss and, paradoxically, creates the most dangerous dry-heat dehydration conditions when temperatures are mild and skies are clear — the breeze feels pleasant but is stripping moisture continuously. Boggy sections between checkpoints can be energy-sapping; gaiters are strongly recommended. Forest trail between the fells often has exposed roots and soft duff, requiring consistent foot placement across the later kilometres when fatigue has degraded coordination. Navigation on open fell between waypoints demands focus; in poor visibility or at night, the lack of obvious landmarks across the tundra makes GPS track adherence critical. Pack layers, wind protection and a reliable head torch regardless of forecast — conditions change quickly across 161 km of Lapland terrain.
Crew & Logistics
The point-to-point format from Hetta to Äkäslompolo means crew must drive between designated crew points rather than having open access to the course. Crew access is confirmed at Hetta (start), Ketomella (31.5 km), Pallas (66 km), Rauhala (87 km), Ylläsjärvi (139.7 km), Kellokas (147 km) and Äkäslompolo (finish). Plan crew transitions carefully: road distances between these points in remote Lapland are not trivial, and crew arriving late to Pallas or Rauhala leaves a runner without support at the two most critical checkpoints. If running without crew, drop bags at crew points become your race management system — pack each one as if it will be your only resupply, because in some segments it effectively is. The Pahtavuoma (98.3 km) and Kotamaja (121 km) checkpoints have no crew access, so runners must carry sufficient food, fluid and kit to bridge from Rauhala to Ylläsjärvi independently across a 52.7 km gap.
