The marathon star and BBC Sports Personality of the Year 2002 won the race in a speedy 30 minutes and 21 seconds.
The race was in San Juan, Puerto Rico where it was very windy and humid.
Faster than ever
But it didn't affect the 28-year-old's speed.
Asmae Laghzaoui had owned the record with a 30:29 win in the 2002 New York Mini Marathon.
This time the Moroccan was second in 31:36.
"I knew from the halfway point on that I was way below my best time," a thrilled Paula said.
