Just a few weeks ago we spoke with Natasha Fraser from the Rivers Gift SIDS research charity, after she had just broken a world record time for running 50km on a treadmill.
Well, her record is not in this year's edition, but Guiness World Records adjudicator Solvej Malouf says she's well on the way to making the cut.
We caught up with Solvej about what does and doesn't make the cut - and what she thinks is the easiest record to break.
Natasha Fraser (pictured below) achieved her 50km treadmill record at the Ballarat aquatic centre gym in a time of 3 hours, 45 minutes and 30 seconds, which is more than five minutes quicker than the previous record for a woman.
We caught up with Natasha shortly after breaking her record at the Ballarat aquatic centre. She is now involved in another Rivers Gift fundraiser - a training program for runners ahead of Run Ballarat on October 22nd.
