Editorial review
We found no Garmin announcement, named regulatory filing or verified retailer listing for a Forerunner 580 in the sources checked on October 5, 2026. This page tracks a possible successor to the 570, using 580 as an unconfirmed name.
Apr–Jun 2027
Our estimate uses 4 releases and a rounded average gap of 24 months, added to Forerunner 570’s 15 May 2025 release, with a ±1 month range. This is a cadence estimate, not a leaked date.
This estimate follows the running and triathlon tier from 245 → 255 → 265 → 570. Treat that lineage as an editorial choice: the 570 changed the tier’s numbering and positioning. We do not copy the longer flagship history used for the 980.
Past gaps: 38, 9, 26 months. Small sample; naming and product strategy can change.
The 265-to-570 change broke the old numbering pattern. 580 is one possible follow-up, while roadmap writers also discuss 575 or 570 Pro. None of those names is confirmed for the next model.
Each entry separates what a source reports from what it establishes. Multiple articles covering one teardown count as one finding. Past forecasts remain visible.
the5krunner lists a possible Forerunner 575 LTE for May 2026 and discusses Pro variants. The same roadmap also places a hypothetical 370 below the 570.
The May date has passed. These are speculative product names, not evidence that a 580 or 575 has been announced. A 370 would address a different tier.
Android Central suggests Garmin could add connectivity to existing models and names a possible Forerunner 570 Pro among the options.
The article is a forecast, not a leak. It supplies no 580-specific specs, release date or certification number.
For a race or training block with a fixed start date, choose from features already available on the 570 and 970. If you want maps or other flagship features, check the current model comparison rather than assuming a 580 will add them.
