What's captured on media and showcased across the internet (as well as what is supported and pushed by the running brands/events) can alter perception of what is valued.
So an Influencer with a family, full time job, and who runs a 2:59 marathon and VLOGs about it (as well as shoe reviews and product) is super relatable to the masses. They can be faster than the average runner and start offering running tips and even coaching advice (As well as shoe recommendations). But also inspiration and little motivational quips. People generally love this and it will get a lot of views and engagement on social media.
A sponsored pro runner is now expected to compete with this (posting high quality videos on social media), but they are simply not going to be as relatable because they are too fast and too serious about the sport (in some regard). They also can't do shoe reviews for a bunch of brands because they are tied to a single sponsor on longer term contracts. They often race longer distance races like marathons less frequently than the influencer...who can do Boston and London on back to back weekends and be called a "hero" for it.
A fast pro also can't really joke around and film during a race and chug beers. But too serious is too much pressure and people like to be entertained.
The "danger" I see is influencers might promote unrealistic expectations. Say they are on banned PEDs and start running crazy fast times for their weight/build. They are cheating and going against the rules of the sport/race, and projecting an unrealistic image of what is actually possible in reality with clean, honest hard work. It is misleading. Might as well jump in a car or cut the course and only run a 25-mile marathon.
Same thing with showing how one might have a bike pacer and/or a film crew and drones and get drinks/aid outside of race aid stations....it's generally against the rules in most races. For every runner.
Then you've got influencers just preaching "Zone 2" and "run streaks" and "hybrid athlete stuff" that can often be a lot of fluff and does more of a disservice to many in the running community if it is inaccurate and/or misleading advice.
It's really inevitable though....I've always said the "pro sponsored athlete" and "influencer" blend together at some point (if one has a large social media following they have an influence...regardless of speed!). For example, I consider myself a coach, a sponsored athlete, an influencer, and a content creator.
Values and what is respected in the sport changes with difference market niches and different social media platforms...it's a dynamic evolution.
My friend Stephen aka "Serious Runner" shows this best:
