There are forever people complaining on this forum "Oh, the cheaterflies are ruining the sport! I'm not watching it anymore!" Let me tell you why that's just being silly:
A) Many, many athletes of the past were very likely drugs cheats who got away with it. Runners who set world records when they're 20 and then had little success after that *Cough*Komen*Cough* clearly were doping in their younger years and stopped due to fear of getting caught/long-term health impact and then never achieved much after that because they reverted to the standard they would've been without the drugs. We still unfortunately have records like the 1500 and mile which were almost certainly not clean so seeing these records wiped from history is a very positive thing for the sport.
B) Seeing records broken makes the sport more exciting and entertaining. If we never had advancements in technology we'd end up at a point where many records are untouchable times set decades earlier and it would make the sport less enjoyable to watch. Who doesn't enjoy stuff like Cheptegei's WR attempts a few months back?
C) Runners have ALWAYS benefitted from technology. Do you think the athletes from the 1950's had all the same access to quality trainers/ facilites etc. as athletes from the 80's and and 90's? Of course not!
D) Just because someone today runs a faster time than someone from the 70's or 80's in no way implies that the modern athlete is 'better'. Obviously running a 2:10 marathon in the 80's was much more impressive than achieving the same thing today. It's not 'ruining' the sport just because someone you watched as a kid is sliding down the all-time list.
E) It's not as though the technologies aren't available to anyone. Sure, the elites get 'early-access' but anyone can now purchase a pair of VaporFly's and Alphafly's. Yes, these things do cost money, but so does everything that will make you a better runner. Eating a balanced diet? Costs money. Getting a massage? Costs money. Visiting a phsyio? Costs money. Travelling to group training sessions as opposed to training alone around your house? Costs money.
