Peake, from Hawarden, narrowly missed out on equalling her own Welsh record of 4.35m as she finished second behind rising star Lucy Bryan.
But the 27-year-old could still be rightly pleased with her performance at her second event of the outdoor season.
Former Hawarden High School student Peake, who is ranked second in the UK behind Holly Bleasdale, said: “It was okay as an opening meeting.
“I struggled a little bit with the conditions because we had a bit of a headwind but I am pleased.
“My third attempt at 4.35m was a good jump so there are plenty of positives to take from this and hopefully I can get a new Welsh record this year.
“It’s also nice to have the ‘A’ standard out of the way so I don’t have to worry about that.
“I’ve done good work in America over the last few months and I am looking forward to going to some good competitions this summer and seeing what comes.”
Peake, who represents Birchfield Harriers, competed for Wales at the Delhi 2010 Commonwealth Games.
