What the 2025 Running Data Actually Shows

Strava's 12th annual Year in Sport report, published in late 2025 and drawn from activity data across its more than 180 million users in over 185 countries, is one of the largest available datasets on how recreational athletes actually train. A few of its findings are genuinely worth understanding if you're trying to make sense of where running culture is heading, not just in India but globally.

Gen Z is driving a racing surge

The clearest signal in the report is a sharp year-over-year increase in race participation among Gen Z athletes specifically. Strava's data shows Gen Z participation up 28% in 5Ks, 39% in 10Ks, 31% in half marathons and 33% in full marathons, compared to the prior year.

The 10K jump stands out. It's the distance where Gen Z growth was steepest, which fits a pattern we've seen discussed elsewhere: the 10K works well as a genuine goal race rather than just a stepping stone, short enough to prepare for without a long training block, long enough to feel like a real accomplishment. See how long is a 10K if you're weighing it as your own next distance.

Walking is now bigger than cycling on the platform

Running remained the single most-recorded activity on Strava in 2025, but the more notable shift is walking's rise: it overtook cycling, hiking and weight training to become the second most-recorded activity type overall. That doesn't mean people are running less. It suggests a broader base of people logging movement of any kind, with walking acting as an accessible entry point that doesn't require the same fitness threshold running does.

Why this matters if you organise or plan around races

For runners: if you're on the fence about registering for your first shorter race, the data suggests you're part of a much larger wave, not an outlier. Race fields across every distance are seeing an influx of newer, younger participants, which generally means larger and more energetic race-day atmospheres at events that lean into that audience.

For organisers, the report's framing is useful too: Strava's own analysis attributes much of this shift to a broader move away from passive screen time toward structured, in-person movement and community, race participation and run clubs specifically included. An event that leans into the community and belonging angle, not just the finisher medal, is targeting exactly the motivation this data says is driving new participation.

A caveat on reading this data

Strava's user base skews toward people who already track their activity digitally and share it socially, which is not the same as the general population of runners. The growth trends are directionally useful and consistent with what race organisers report anecdotally, but treat the specific percentages as describing Strava's own community, not a scientifically representative sample of every runner everywhere.
