According to the source review from TechRadar, Apple’s latest watchOS 27 update introduces enhanced treadmill workout distance tracking through refined motion detection algorithms. The reviewer tested this improvement over several months using multiple Apple Watch models alongside the Coros Pod 2, a foot-mounted sensor used as a control, to assess tracking accuracy indoors.
- Improved distance accuracy on treadmill workouts via enhanced algorithms
- Tested using multiple Apple Watch generations plus Coros Pod 2 as control
- Notable accuracy improvements especially beneficial for longer indoor runs
Product angle
The source review reports that the Apple Watch’s watchOS 27 update focuses on refining treadmill distance measurement by leveraging advanced motion tracking algorithms. These adjustments enable the watch to better estimate indoor running distances directly from wrist movement, addressing previous inconsistencies common with indoor running. Testing was conducted over several months with various Apple Watch iterations including Series 11, Series 12, Ultra 3, and Ultra 4 versions.
The evaluation methodology involved simultaneous use of the Apple Watch on one wrist and a Coros Pod 2 on the foot, which served as an independent tracking device for benchmark data. This allowed the reviewer to identify differences in treadmill distance readings across different sessions, paces, and test scenarios. The results showed a marked reduction in variance from earlier watchOS versions, confirming the update’s success in providing more precise indoor workout data.
Best for / avoid if
This update is best suited for runners who frequently incorporate treadmill workouts into their routine and desire reliable distance metrics from a single device worn on the wrist. Users preparing for longer distance indoor runs or interval training can particularly benefit from the improved consistency and closer alignment to external validated tracking devices like foot pods.
However, this solution might be less ideal for users who require extremely precise short-distance tracking or depend heavily on treadmill readings for split-second accuracy in competitive racing contexts. The small remaining discrepancies could impact those needing exact data over short distances like 5K runs or sprints. Additionally, casual users without treadmill usage may find little immediate benefit from this update.
Pricing and alternatives to check
While the review does not provide specific pricing details for the Apple Watch models or watchOS update, Apple Watch pricing generally ranges based on model and features. Buyers should consider the cost of the watch hardware along with potential tradeoffs when selecting among different generations. No dedicated subscription or additional fee is required to access watchOS 27’s treadmill tracking enhancements once updated.
Alternatives to assess include devices and systems that rely on foot pods or external sensors, such as the Coros Pod 2 used in the test. Some runners may prefer hybrid setups combining wrist-worn smartwatches with foot-mounted devices for improved precision. Other smartwatch brands with strong treadmill tracking capabilities, like Garmin or Polar, might also be worth evaluating depending on user needs and budget.
