London Marathon winner Paula Radcliffe has claimed she is capable of beating her new world record.
Radcliffe destroyed her own previous world record by almost two minutes in Sunday's London Marathon with a devastating display.
But the 29-year-old maintained that she has yet to reach her peak.
"It's not in my mind that I can't run faster," she said.
"I don't think any of us like to say we have reached our best because you don't know.
"You have to hope that you can keep running faster."
And she dismissed clams that the use of male pacemakers artificially boosted her time.
The next time I am likely to run a marathon is likely to be in the Olympics
"I don't think it made much difference," she said.
"I still feel like I ran 26.2 miles as hard as I could."
Radcliffe has set her sights on an Olympic gold medal to complement her Commonwealth and European titles.
"The next time I am likely to run a marathon is likely to be in the Olympics," she said.
"It's not likely to be before then."
Third-placed Deena Drossin was full of praise for her rival's performance.
"It was an impressive performance by Paula - I can't wait to see the clips of it," she said.
"I think it's an inspiration to other runners to make little extra sacrifices, to start training at a higher level to try to close the gap again."
