Hi Cheetah thanks heaps for the points you have put across, I'll do my best to give you some info on some of them!
First up I'd like to quickly say I have a 60m then 100m race tomorrow! Since my 12.90 run I have done 3 sprint sessions and maybe 5 heavy leg sessions while being careful of a minor foot injury, so I'm interested to see if I make any improvements. I will post a quick/short update on here tomorrow after the run. Ps: I also got my first track shoes in the mail today! Nike Zoom Rival S 9's. Excited to see if they make any difference.
My goals for tomorrow: 60m - 7.99 seconds. 100m - 12.49 seconds. I'll consider hitting either 1 of these a win for the day.
So to answer some of your points!:
I'm hoping to do this progression over a 3-year timeframe as you mentioned in your 5th point. My first years' focus is to lose all this body fat. I am currently at 28% body fat (23.1kgs of body fat on my 82kg body) so once I drop that down to about 15% (losing 11kgs/25lbs of fat), I think I will have a much clearer idea of where I stand in the 100m.
To give insight into your second point, I paid for an in-depth body scan which analysed everything about my body down to which leg/arm was stronger than the other, visceral body fat, etc, etc. It was extremely helpful and gave me a boost in motivation to keep losing weight. It revealed that my body fat percentage was 28%. For men, I believe obese is defined as 25% body fat percentage or higher, borderline obesity is defined at 21-25%, therefore I sadly still sit (pun intended) in this range, however I have definitely dropped my percentage over the last 90-odd days (81 gym sessions, 11 long-slow cycling sessions, 7 swimming sessions and now in April, a few sprint sessions, coupled with a healthy diet, resulting in losing approx. 7kgs/15lbs of fat).
In response to coaching, sadly I live in a small town of 80k people. In Australia and in my country region, track and field is extremely small. The club I just joined doesn't even have weekly training sessions, people just come on Saturdays and do their events. The club looks like it sometimes has people up from the city running clinics but that is it! I will be making the most of YouTube to grasp some sprinting knowledge and see where I end up in 12 months :)
One thing I am really hopeful about, and I would love peoples thoughts on this, is that my initial 100m at 87.5kgs was 13.68 (hand timed). When I hit 82kgs I ran 12.90 (electronically timed, about .80 better time). Of course, things aren't straight forward but I'd love to think that another 5kgs of fat loss will result in perhaps .50 off this time, and another 5kgs perhaps another .40, getting me to around 12 seconds flat just from not carrying all this fat around (one can hope!). I have heard spiked track shoes can get around .25 off a 100m time as well (compared to the 11oz runners I used) and perhaps technique/added flexibility might shave another .25 off. Then I feel it will come down to my pure hard work and specific sprint training program to see if I can shave the next 0.5 second off! This is simply me overthinking everything because nowadays when I'm not training all I do is watch videos after videos of sprinting! I'm addicted right now.
Lastly, YES I am having so much fun doing the sprint training, it makes me feel alive and fit again even though I'm not quite there yet.
Thank you for the in-depth message, I will continue to keep working hard and making improvements happen in my body and on the track. Keen to see how I go tomorrow on the Track.
