Garmin's social-fitness ambitions just got more obvious. The company has begun rolling out a new transparent activity overlay inside Garmin Connect that lets runners drop pace, distance, heart rate and elevation onto their own photos and clips, then export the resulting graphic to whichever social network they please. The feature is functionally indistinguishable from Strava's long-standing photo overlay tool — and that, more than anything Garmin's marketing team is willing to say out loud, is the point.

The overlay menu sits inside the activity detail screen on the latest Connect mobile build. Tap an existing photo or video, choose which fields to show, and Garmin renders a tidy, semi-transparent stat panel that respects the underlying image rather than blocking out a third of it the way the older "achievement card" did. Field choices include splits, average pace, total distance, average heart rate, elevation gain and the company's own running power and ground-contact-time metrics, all of which Strava cannot read natively. The result, in early testing, is a card that genuinely looks like the work of someone with access to actual sensor data.

For runners, the practical question is whether the overlay is enough to drag them back into Garmin Connect for sharing rather than firing up Strava. The honest answer this week is: it depends on how often you film yourself running. The transparent layer behaves better than Strava's equivalent on mid-run video clips, where the dark bars on the original Strava cards have always crowded the action. It is also marginally faster: Garmin renders the overlay locally rather than uploading to a server first, which matters on a tube platform after a long run when phone signal is patchy.

What Garmin does not yet have is the social graph. Connect's feed has improved steadily over the past two years — weekly summaries, comments, group challenges — but Strava is still where most serious runners maintain their kudos relationships, and the new overlay alone is not going to overturn that. The interesting move would be Garmin opening its overlay to non-Garmin data the way Strava does, or alternatively Strava replying to this with a more flexible canvas that can host third-party metrics. Neither company has commented on what comes next, but the cadence of feature releases this spring suggests both teams are watching the other in detail.

The wider context is the same one that has shaped fitness tech since the start of the year. Strava's 12th annual Year in Sport report showed activity logging up sharply, with walking joining running near the top of the platform and Gen Z driving a noticeable shift towards strength training. Garmin's own data showed an 8 per cent rise in total activity logged. Both companies are now competing not just for runners but for everyone holding a phone in the gym or on a hike, and the tools each platform builds for sharing what you did are increasingly the front line of that fight.
