Murray now secured a place on the British team to compete at the European Championships in Poland in July.
Murray, ranked three in the world, won bronze at last year’s World Championships and silver at London 2012, but hadn’t yet won a senior British Championships.
The 23-year-old did it in style today in a high class field that also featured Beijing 2008 Olympic silver medallist Heather Fell and reigning world champion Mhairi Spence.
After an impressive day, Murray shot and ran strongly at the Tudor Grange Leisure Centre to finish 20 seconds clear of 17-year-old Eilidh Prise.
It meant Murray captured the senior and overall titles, with Aberdeen teenager Prise, a member of Pentathlon GB’s World Class Podium Potential programme, impressing with the fastest run/shoot time of the day en route to the junior title.
Murray is now focussing on studying for her finals for her French and Politics degree at the University of Bath later this month.
“I had a fantastic day,” she said afterwards. “I was relaxed coming here and I wanted to win to secure my place at the European Championships.
“I started training again after the Olympics in January and I felt strong today,” she added. “My running has improved since the World Cup in Rio last month, when I finished fifth.”
Murray started the day well with the second best performance in the fencing, winning 33 of her 42 bouts. That was only bettered by Jenny McGeever, with 35 wins.
Kate French and Katy Burke were joint third with 30 wins, with Eilidh Prise fifth, Spence and Freyja Prentice joint seventh and Fell 11th.
Murray climbed to the top of the leaderboard in the swim, and from there she never looked back. Her 200m freestyle time of 2:09.96 was the second fastest of the day.
Burke moved up to second with 2:11.78, the third fastest time of the day, with McGeever third and French fourth. Alice Fitton clocked the fastest time in the pool with 2:08.42 to go joint fifth with Eilidh Prise.
Murray extended her lead in the ride. She had one fence down and also sustained some time penalties to add 1120 of the maximum possible 1200 to her score.
That meant she went into the run/shoot 92 points and 23 seconds clear of Burke in second. Burke added 1112 points to her score in the ride.
Eilidh Prise and Spence were the only two riders to go clear in the allowed time to bag the maximum 1200 points in the arena at Solihull Riding Club. That was enough to promote them from sixth and seventh respectively overall to third and fourth.
Fell, meanwhile, went into the run/shoot in 14th, climbing from 11th place after the swim.
Murray shot and ran well to make sure of the title, although Prise’s 12:28.06 run/shoot was six seconds quicker than that of the London 2012 medallist.
French came home third, with Burke fourth and Fell producing a battling end to her campaign, scything her way through the field from 14th to fifth. Spence finished seventh
