Dragon's Pass really hit her straps on the run-in to rocket home in the two and a half mile handicap hurdle at Navan.
There was an absolute stack of horses in with chances over the second last in this big field but it was strong-travelling Solar Heat who moved to the head of affairs.
Sean Flanagan began to get more than a tune out of Dragon's Pass in third on the run to the final flight and the pair stormed past Solar Heat in the final 100 yards.
The four-year-old filly's finishing burst was impressive as she she won going away by a healthy three and a quarter lengths at 10/1.
Solar Heat (20/1) was booked for the runner-up berth once collared and came in ahead of The Dreams Alive (12/1) and Upourdat (50/1).
Trainer Denise Foster said: "That was a little bit unexpected. This is the first time she's gone that distance and it looks like she's crying out for it.
“She really tried out there, she likes that ground and now I know what trip to run her over.
“We'll keep her going over the winter now that we know she likes heavy ground.
“I'm delighted for the owners as they've been very good supporters of mine for many a year.
“Sean gave her a great and said she actually took him into the race which is great. She had a good few runs on the Flat to sharpen her up.
“She's a beautiful-looking mare and I'm delighted to get that for the Newells.”
This was a first career victory for Dragon's Pass on her 16th start (seven races on the flat and nine over hurdles).
