Check out either the page Training » Pulse Ox Acclimation, or the section Reports » Health & Fitness in Garmin Connect Web. There is also an export function accesible through the symbol top right above the chart.
Hi, thank you so much. I tried but don’t have the Pulse Ox Acclimation on the training side, and on the reports I only have activities... I wonder why you have additional functionalities on your profile vs mine... ?
