There are plenty of people in gyms all across the land who train, eat a certain way and take steroids just to look good on instagram/big whilst doing the door somewhere. They don't earn any money out of it, quite the opposite, it costs them money. And nobody outside of what they are doing gives a sh1t, no money/fame/glory awaits. And yet they do it anyway.
Then there are other people who go further, and get into bodybuilding...and will enter "natural" contests (where they are supposed to be drug free) and cheat to win a title that nobody outside of that little niche circle gives a toss about, again not making any money out of it.
It is in the mindset of humans to gain an edge, even for piddly stuff like the above. So it seems like common sense that in higher profile sports, where the fame/glory/money is much greater, a lot of the participants will do whatever it takes to win and lie their arses off about how they achieved it.
I say, let them do whatever they want, instead of giving them rules that they have to break in secret. They still have to put the work in riding the bike/lifting the weights/running the track etc etc.
Usain Bolt is a nice guy, charismatic etc. But if he ran the hundred meters no quicker than 10 seconds, nobody would give a sh1t about him. The people love him because he's a freak who destroyed world records and they always wanted to see him obliterate the competition. The viewing public have an insatiable need to watch the best ever, the biggest, fastest, toughest, undefeated, undisputed champions. And then they cry when it turns out the hero of the day got caught breaking an arbitrary rules that other people got away with breaking. Maybe he was always drug free, maybe he could cheat better than other sprinters. But I loved to watch him run anyway.
Just appreciate the best for what they do imo. Anyway, I will let you get back cycling now!
