— -- Mothers know that delivering a baby can sometimes be a marathon and sometimes, if you’re lucky, a sprint.

The world’s most famous expectant mother, Duchess Kate, may find herself literally in the midst of a marathon if she goes into labor with her second child Sunday.

Kate, 33, and due any day now, is waiting out her pregnancy at her and Prince William’s home in Kensington Palace, which happens to be right in the heart of London, a city hosting its annual marathon Sunday.

Royal Baby Birth: 7 Things We Know to Expect

The 2015 London Marathon will see over 30,000 runners take to the streets to run the 26.2-mile course.

The thousands of runners, and their fans, will join an already crowded city full of royal watchers who have been camped out at St. Mary’s Hospital, where Kate is expected to deliver, for days.

“Been here since last Thursday,” one royal superfan, sleeping on a bench outside the hospital, told ABC News.

Duchess Kate has said only that she is due sometime between mid-April and the end of the month. The longer Kate is pregnant, the greater the chance the baby’s uncle, Prince Harry, could make it back to London for the birth.

Harry, 30, has been stationed in Australia as part of a month-long exchange program with the Australian Defense Force. Both he and his father, Prince Charles, the baby’s grandfather, will be attending the ANZAC celebrations in Gallipoli, Turkey, Saturday.

Prince Harry will then make a quick turnaround to return by Sunday to London, where he will help hand out the medals to the London Marathon winners. A Saturday or Sunday royal baby birth would mean Harry may get to meet his second nephew before he has to return to Australia.

“We are so close to the due date now,” ABC News royal contributor Victoria Murphy said. “William and Kate are at Kensington Palace, ready to go, just a short drive to the Lindo Wing.”
