Desiree Linden has become the first woman to run 50km in under three hours, breaking the world best with 2:59:54 at a specially-organised event in Oregon, USA, on Tuesday (13).

With that time, the USA's 2018 Boston Marathon champion takes more than seven minutes off the previous world best mark of 3:07:20 which had been set by Britain’s Alyson Dixon when winning the world 50km title in 2019. The previous ratified US record had been Janis Klecker's 3:13:51 set in 1983.

Two-time Olympian Linden is no stranger to running long distances – as well as her many marathons, she completed a 496-mile ‘Destober’ challenge in October which saw her run a mile for each calendar date through the month – but this was her first official ultra-running event.


On a loop course in Oregon, Linden – who has a marathon PB of 2:22:38 set in Boston in 2011 – averaged at a pace of 5:47 per mile for the 31 miles (3:35 per kilometre), clocking 1:15:47 at the half-marathon mark.

Being paced by Charlie Lawrence, her time at 30km was around 1:47:30 and her marathon split was 2:31:13.

Lawrence clocked 2:59:59 for the 50km, while Romania's Adriana Nelson won the marathon in 2:35:26. 

Chirine Njeim, who competed at three Winter Olympics in alpine skiing before racing the marathon at the Rio 2016 Games, improved the Lebanese marathon record with a time of 2:36:40.

The event – named the Brooks Running 50km & Marathon – had been organised by Linden’s sponsor and her agent, Josh Cox, when her original plan of racing the Two Oceans ultramarathon in South Africa was cancelled due to the pandemic.
