Black River Run 50 miles

Black River Run 50 miles

This page covers the Black River Run 50 miles in 2026. Five laps make about 80 kilometres and around 550 metres of climbing, and every lap has the same rhythm: narrow trails and bare rock for the first five kilometres, a checkpoint with water and sports drink at 5.9 km, the fast stretch downstream along the Svartån river, and finally the short, steep climbs up under the E18 bridge toward Orientalen. The lap point has a well-stocked table, a tent for your own food and spare clothes, and toilets inside the club hut.

The limit is 30 hours, as for every distance, but for most runners this is a day that ends at dusk. The organisers point out that many 50-mile runners will need a light toward the end: anyone starting a new lap after 18:00 must carry a headlamp, spare batteries and a spare lamp. The first kilometres of that fifth lap are also the most technical of the course, with stones and roots that get slippery in the rain.

Five passes of the lap point tell you where a runner was, not where she is. With Livebib the runner shares a link to their own broadcast, and family and friends see in a browser, with no account and no app, the position on the lap, the distance done and a finish estimate that updates through the day. When the phone loses signal the position is carried forward along the course and marked as estimated, so whoever waits at the finish knows roughly when the headlamp will come out of the trees.
