In the final stretch of the 2012 London Marathon, a 30-year-old woman collapsed and later died.
According to DailyMail.co.uk, Claire Squires fell to the ground in the last mile of the 26.2-mile race. She received medical attention but unfortunately passed away.
The cause of her death is not known at the time, but tests are being run to figure everything out.
She dropped to the ground at Birdcage Walk, near St James' Park, which is the last road the competitors run on before approaching Buckingham Palace.
Officials of the London Marathon released a statement on their website to those who knew Squires.
The organisers of the Virgin London Marathon would like to express their sincere condolences to the family and friends of the deceased.
Squires was running for charity and had raised nearly £500 before the race, but after the news of her death, the totals for her fundraiser on JustGiving.com have now skyrocketed to over £8,000.
On her fundraiser page, her statement about why she was running says, "I'm running the London marathon for Samaritans because they continuously support others."
Many folks have shown their support and love for Squires with messages on her page.
This is the 10th time someone has passed away in the London Marathon since it began in 1981. The last person to die during the race was a 22-year-old in 2007.
