On 6th October 2026, 193 runners left Sheffield at 4am on and shuffled the 77km across the glorious Peak District to arrive satisfied, exhausted, but in one piece – just about – in Manchester that evening. The 4th edition of Peak Divide’s ONEr Ultra Marathon event was a hit once again.
Run in partnership with Altra Running Europe, the ONEr is an alternative to the summer’s Peak Divide event, which goes in the opposite direction to the summer’s event and covers the distance in one go, as opposed to including an over-night stop.
Proudly a bit less serious than your standard ultra, it’s at the checkpoints where it gets properly Peak Divide. This year’s menu ran from Dam-top Silver Service to Kinder Surprises. Live tracking was new for this edition and it’s staying. Two runners also started from Edale and ran a trail marathon into Manchester, a format Peak Divide is calling the PD DEMI. More on that from them soon.
The ONEr is back in 2027.
We spoke to Tom and Stef about how it all came together. Read the interview here.
