Word: "ratio" appropriate here? Can you correct my sentence?

Word: "ratio" appropriate here? Can you correct my sentence?
 

Spanish word: ratio
(is it appropriate here or should I use a different word?)

My original sentence?: Fue la primera que vez corrí un ratio surpiero nueva minutos por milla.
(Can you correct the sentence?), (Thank you for correcting it or any other help you offer!)

Extra info: I write a personal diary in Spanish then i use Google translate, ChatGPT, Grok, and web search to help correct my writing but this time they all disagree and am curious to know what a real human thinks? In the sentence i wanted to communicate in terms of minutes per mile that I runned faster today then previous days.

Note 2: i wanted to post a photo of my Spanish journal and running app but i can't seem to do it with mobile. If anyone wants to see it I'll might try to again on desktop. My app claim my average took me 8:59 minutes / mile keep in mind i only run a third of a mile. I'm working my way up to a whole mile.

Note 3: if anyone wants to read it here is a type out version of my whole diary entry before any corrections (it's probably pretty lame and boring jaja):
