The rise of the ‘runfluencer’ on Instagram, and who to follow this marathon season (& beyond)
Scroll through IG (or TikTok) right now and you’ll probably notice a recurring theme. Alongside race-day snapshots and training vlogs, a new type of creator has taken centre stage: the run influencers, aka. ‘runfluencers’.
Marathon season, that stretch between March and May in the Northern Hemisphere, is usually when we see running content hit the mainstream, drawing in everyone from seasoned marathoners to people lacing up for their very first Couch to 5K.
Here at TRB, we spend a lot of time online tracking the creators and conversations shaping the wellbeing space. From fertility and women’s health to fitness and lifestyle trends, we’ve seen how social media communities influence the way people discover products, build habits, and connect with brands. Running culture is one of the clearest examples of this, right now.
Here’s our take on the rise of the ‘runfluencer’, why audiences connect with them so strongly, and the creators worth following this marathon season, whether you’re looking to get in on the hype as a brand or a new runner.
The rise of the ‘runfluencer’
The rise has been gradual but noticeable since around 2020, when everyday runners began documenting training cycles more intentionally. Instagram Reels accelerated it further, turning long-distance running into short, engaging storytelling moments, from early-morning interval sessions to carb-loading routines and race-day nerves.
What started in niche running communities has now moved firmly into the mainstream – check out our piece on Gen-Z wellness influencers for more on this shift. You see it across London Marathon build-ups, New York training blocks, and local park run content that regularly reaches beyond fitness audiences. Going beyond your regular lifestyle influencer content, training discipline, lifestyle content and wellbeing habits overlap naturally.
Search terms like how do I start running have gone up by +70% over the last five years, and now frequently surface alongside influencer-led content. That visibility has helped ‘runfluencers’ move from hobbyists to recognised voices in the wellbeing and lifestyle space.
What we’re reading about running influencers
As the ‘runfluencer’ space grows, so does the conversation around it, naturally.
On one side, you see strong appreciation for the accessibility they bring. These everyday runners share training highs and lows in a direct and relatable way. They do often give a sense that you’re following a real person, rather than someone’s highlight reel.
You also see chats around credibility, especially on the Reddit running threads. Some audiences question advice shared online, (think AI training plans and falsified personal bests, eek!)
Fair enough, especially when creators are seen to be growing quickly through viral moments. This has encouraged many ‘runfluencers’ to be more transparent about their qualifications and training methods, plus what comes from personal experience versus professional guidance. Fair.
Another common theme is representation. Running content on Instagram has historically leaned towards a narrow visual narrative. The newer wave of creators is broadening that picture, showing different body types, paces, backgrounds, and training styles. We’re here for it.
There’s also a growing awareness of how brands show up in this space. Audiences tend to respond well when partnerships feel integrated into training life rather than layered on top of it.
Our take on this last point? Authenticity remains the deciding factor for whether sponsored content resonates.

The running influencers landscape continues to evolve as marathon culture grows more visible online.
What stands out most (we think) is how it blends personal storytelling with structured training content, creating a space where audiences can learn, follow along and feel part of the journey, one run at a time.
