River Run & Optional Sauna

Up the Alnaelva to the edge of Østmarka — sauna optional

Distance: 14 km
Pace: Steady, gentle climb out and easy return
Duration: About 1 h 45 min, plus sauna
Group size: Max 8

Most visitors run the Akerselva. This is the local's other river. We start by Kværnerfossen in Kværnerbyen, where the waterfall drops behind the old industrial buildings, and head straight into Svartdalsparken — a steep, green gorge that feels like proper forest ten minutes from the city centre.

From there the Alna river path climbs steadily north-east through parks, reopened river stretches and old industrial Oslo, out to the edge of Østmarka roughly 7 km up. We turn there and run the same way back, mostly downhill.

The run can finish with a sauna at Kroloftet, a short walk from the start. I arrange towels and the booking — just say so when you book, and let me know if you want the sauna included (Additional 240 NOK sauna fee per person). The full run has roughly 290 meters of elevation gain. If this feels too much, let me know and we will adapt!
