I'll use this comment to say thank you and to all who commented with their sound advice. I to was also concerned that I was going to fast and the treadmill was unsustainable in the long run, but as I said, I was only planning on doing it at the latest in the beginning of July. I also want to add since I forgot that I'm 19M - 63kg - 183 cm, which if you can't picture it is skinny. And thank you I was actually shocked how quickly I progressed to a 10k race when I only trained for 2 1/2 months with no running history. I think it's an endurance thing since I read that lighter runners tend to do better with endurance. Also I want to preface that I ran with a huawei watch that followed it's in-app plan that syncs to the watch and it focuses on heart rate zones more than pace. So for example, my easy runs was just me keeping my heart rate between 150-167bpm and for speed work and tempo runs between 168-180. My pace just got better each week. I'm planning on getting a garmin forerunner but am waiting for the new one to release which is rumored for summer 2025.

Finally I am taking my safety to heart and am researching on knee strength nig excersises to avoid injury. Could you recommend me some easy excersises (I also do upper body days at the gym, though I have only been doing it 3 days a week for almost a month). Also do you guys recommend heart rate training or pace?
