Valencia produced half-marathon performances faster than the standing US and European records, but neither counts toward those records.

Elsewhere, a Garmin running-power guide and a treadmill app test highlight limits in interpreting wearable data.
Valencia performances beat US and European record times but do not count
Yaseen Abdalla ran 59:12, faster than Conner Mantz’s 59:17 US record, but does not become the record holder. A Spanish runner’s 58:03 counts as a Spanish record, but not a European record; Andreas Almgren’s 58:06 remains the European mark.
Why it matters: The distinction matters when comparing race performances with officially recognized national and continental records.
Garmin running-power guide explains readings roughly 30% above Stryd
The guide reports that Garmin’s running-power readings are roughly 30% higher than Stryd’s because Garmin counts mechanical work. It also notes that Garmin’s wind input comes from a forecast and discusses two studies.
Why it matters: Runners switching between systems should not assume that power readings or training targets are directly interchangeable.
Klemy Treadmill app shows lower distance error in developer test
Klemy Treadmill takes distance from the treadmill belt. In the developer’s one-hour test, the watch alone over-read distance by 1.2 km, or 16%, compared with 1% for Klemy; this was not an independent test.
Why it matters: The app offers a potential alternative for indoor distance tracking, though the reported accuracy needs independent validation.
