McColgan is hoping to build on a successful 2022, when she won Commonwealth Games gold in BirminghamEilish McColgan set a new British 10,000m record in California as she continued preparations for next month’s London Marathon.
The 32-year-old Scot ran 30 minutes 00.86 seconds in her first track race of the year, beating Paula Radcliffe’s time of 30:01.09 set in Munich in 2002.
McColgan has been training at altitude in Colorado and made a late decision to race at the Soundrunning Ten event.
“I’m absolutely buzzing,” said the 2022 Commonwealth Games gold medallist.
“Two years ago I ran a big PB [personal best] here so it’s nice to be back with the crowds. I knew I was in really good shape but to have it all come together on the day doesn’t always happen.”
McColgan, who has been dealing with some knee problems in the build-up to her debut marathon on Sunday, 23 April, now holds British records for 5,000m, 10,000m, 5km, 10km and half-marathon.
Meanwhile, fellow Briton Emile Cairess, who will also be making his marathon debut in London, has broken the European 10-mile record.
The 25-year-old clocked 45:57 at an event in Barrowford, Lancashire, beating Richard Nerurkar’s long-standing mark of 46:02 set in 1993.
Last year Cairess equalled Mo Farah’s UK 10km record before running a half-marathon PB and then finishing second in the European Cross Country Championships in Turin in December behind Norway’s Jakob Ingebrigtsen.
