The 22-year-old world and Paralympic champion, who is working under new coach Leon Baptiste, lowered her own world record at the Loughborough International in May.
"I just love competing in that stadium and I know the track is great for me," she told BBC Sport's Katie Falkingham earlier this week. Read more of that feature here.
Olivia Breen, Hahn's Welsh rival, and World and Paralympic 400m champion Kadeena Cox is likely to push Hahn hardest.

T53/54 800m Men
And Dillion Labrooy pulls off a perfect heist of Richard Chiassaro, sitting on his back wheel down the back straight and burning off the favourite to win in 1:38.13! Danny Sidbury takes third.
That was canny.

Richard Kilty: "We had fun and were relaxed and were able to let loose on every leg. That's an amazing performance."
That was Britain's second-fasted 4x100m relay performance off all time.
The only team to have gone faster were the gold-winning foursome at the London 2017 when Ujah, Gemili, Talbot and Mitchell-Blake ran 37.47 seconds.

Two-time world 110m hurdles champion on BBC One
That was a very strong run. Each of them know they are running for their place in the team and know they have a chance to be world champions in Doha.
That's a super fast time, a great performance from all of them.
Richard Kilty ran a tremendous bend and Mitchell-Blake was strong and flawless on the final leg, with no tension and he just enjoyed his running.
4x100m relay
Nethaneel Mitchell-Blake brings home the GB quartet in 37.60 - half a second faster than the GB team managed in the World Relays earlier this season and a world-leading time.
That is punchy. Where do Adam Gemili and Reece Prescod fit back into this team? Do they?

Shelly-Ann Fraser-Pryce was a ball of power in the 4x100m relay yesterday, she produced her old vintage form, with perfect technique and she got the victory for Jamaica.
It's been fantastic watching her compete against Elaine Thompson.
She is back sprinting well and we will be in for a fantastic 100m in Doha later this year.

"Sometimes I do tell myself, 'you can't, you can't', when really I should be telling myself I can,"
She definitely can.
The number one 100m sprinter in the world according to the IAAF rankings, Dina Asher-Smith takes on the event's royalty today with Shelly-Ann Fraser-Pryce and Dafne Schippers.
It is the headline act on day two of the Anniversary Games.
