Davies, 26, followed up sealing her World Championship place in the 20km by setting two new British bests in the mile and 5km event.
The Cardiff walker won the 5km at the British Championships in Birmingham.
"It's been a very good week, all the hard work has paid off," said Davies.
Davies competed in three events in seven days which began with achieving the London 2017 qualification time when she finished in a Welsh record 93:04 behind Gemma Bridge.
Davies will be joined by Bridge and Tom Bosworth and Callum Wilkinson at the World Championships next month in London (August 4-13).
"It is unbelievable," said Davies.
"I probably when I was younger never expected to get to this level of sport.
"It hasn't sunk in yet and when I get there I will probably have to take a few moments.
"It's absolutely fantastic to be on the same stage as such big names.
"This will be the biggest competition I have ever been to and it will be a big step up."
Davies will now take part in a three-week altitude camp in Livigno, Italy and St. Moritz, Switzerland and attend a British Athletics holding camp in Paris before her event on 13 August on the Mall.

"It will mean so much because the first chance I saw race walking was at London 2012," said Davies.
"To go from a spectator to the start line alongside the girls who have inspired me and are now my friends and rivals will be amazing.
"It is going be a home event where all my friends and family will be watching.
"Growing up, the thing I remember was watching the London Marathon finishing on the Mall.
"To be there and doing my sport at the highest level is going to be amazing."
Davies believes walking is receiving a higher public profile.
"From when I started it (walking) has grown," said Davies.
"We are getting more attention which has been helped by Tom Bosworth coming sixth in the Olympics last year which has raised the sport's profile.
"Race walking is a really good way to get people drawn into athletics."

Pakistan's 42-year-old Test captain Misbah-ul-Haq and 40-year-old batsman Younis Khan complete the list.
India captain Virat Kohli, 28, was named leading cricketer in the world, while Australia's Ellyse Perry, 26, was the world's leading women's cricketer.
The coveted awards, which began in 1889, are a central feature of the annual Wisden Cricketers' Almanack.
Its editor said 2016 was the year Woakes, 28, "announced himself as an international-class all-rounder".
They praised the 26 wickets the Warwickshire player took over last summer's four Tests against Pakistan, and the unbeaten 95 he scored in a one-day international against Sri Lanka at Trent Bridge in June.
Northamptonshire batsman Duckett, 22, was singled out for his "remarkable" run total of 2,706 across all formats of the game last year.
"As much as anyone, he epitomised English cricket's new breed of 360-degree batsmanship," it was added.
Roland-Jones, 29, who was called up to England's Test squad for the first time in July, picked up a hat-trick for Middlesex as they secured a first County Championship title in 23 years in September.
Wisden editor Lawrence Booth described the feat as "the highlight of the domestic summer".
Younis' "classy" 218 in Pakistan's final Test against England at The Oval was "a reminder that his struggles earlier in the series had been a blip rather than part of a decline", Booth wrote.
Misbah's celebratory press-ups after an unbeaten century in the first Test at Lord's were described as "one of the motifs of the year".
Australia all-rounder Perry "seemed to be operating on another level" over a year in which she averaged 81 with the bat in one-day internationals, taking her record between 2014 and 2016 to 17 half-centuries in 23 innings.
And India captain Kohli's double ton in Mumbai confirmed him as "the spiritual successor to Sachin Tendulkar".
Welsh walker Bethan Davies says the hard work has paid off after qualifying for the World Championships in London and setting new three personal bests in a week.
