Lizzie Armitstead won the British Cycling National Women's Road Race Championship in Glasgow by 63 seconds on Sunday.
The Boels Dolmans CT rider finished just over a minute clear of second-placed Laura Trott and third placed Danielle King after breaking away on the final lap of the Glasgow city centre circuit.
The Olympic silver medallist went all out on the eighth and final lap of the 112km race, putting space between her and her rivals on the last climb of the University hill.
Armitstead said: "I didn't want to show my cards too early and if I tried to go on the steep climb I knew I'd probably have a bit more power over the track riders who are used to shorter distances so I used that to my advantage, played a bit of a poker face.
"I was kind of waiting for it all race really, Dani lead all the last lap and if I was them I would have continually attacked me, but maybe they were confident of beating me in a sprint, but I wasn't letting it go to a sprint."
Sandy Wallace Cycles rider Anda-Jay Burgess led an early attack, but the peloton was whittled down to a group of 18 elite riders mid-way through the race.
Trott, Armitstead, King, Amy Roberts and Emma Trott then led a mini-escape opening up a two minute gap over the peloton.
On the penultimate lap Armitstead attacked, but dropped Boels Dolmans CT teammate Emma Trott, leaving her isolated up against Wiggle Honda colleagues Laura Trott and Dani King.
Eager to avoid a sprint finish, the Boels Dolmans CT rider broke clear of Laura Trott and King, opening up a 10 second gap on the final lap - a lead that extended to over a minute by the time Armitstead crossed the finish line in first place.
