Just to answer your comments re: high school and sports, I was 3rd fastest in high school in my senior year with no track experience. I also stopped playing soccer after my junior year and was the fastest player on the team, also with no sprint/track training. 4 years ago I joined an local men's prems soccer team, came into first training as the fastest player (stopped playing beginning of 2018).
I think what many people are forgetting is I come from a rural town in Australia. We don't have scouts for track or anything of that nature and Track and Field is not a big thing in my region. In fact our town just got our first 'real' 400m track 3 years ago (with the correct track surface). My 12.40 run today which cut 0.5 off my previous time in March was against two 14 year old girls because there are literally no opens men running in my town of 80k people. That's just the reality of where I live, which is totally okay. It seems some people are using their own societal circumstances to comprehend the situation and not understanding what I have had available to me.
The reason I got fat was from a job I landed in a coal mine 3 years ago. We were given free food, accommodation and travel, and when I wasn't working I was eating as much as I could. We could even take as many frozen meat pies home for the weekend as we wanted... From Jan 2018 - August 2018 I went from 73kgs to 82kgs and have struggled to lose it since then, eventually reaching 87.5kgs in Jan 2021. Unfortunate situation, but I'm doing something about it now and just weighed in at 81kgs!
I feel like once I hit 72kgs we will all have a much better idea of where I stand in the 100m. My guess based on how my body feels currently is I will be in the mid 11 range. Then it will be grinding the last 0.50 off.
