new VO2max Features For Fenix & Forerunners ... and Enduro

new VO2max Features For Fenix 6 & Forerunners ... and Enduro? I was trying to keep my powder dry on the new features that will appear in next month's supposed Garmin Enduro launch, except Garmin keep releasing them in beta for some Forerunner & Fenix models. #Sigh. Recommended: Garmin Fenix 7 Review new ClimbPro We've already seen the new ClimbPro alerts and ClimbPro descents make their way into the 945 beta last week. 2. new VO2max for Trail Runs I'd missed that new VO2max is now calculated for trail runs in the latest Fenix 6 beta (see Garmin Forum). That info was leaked last year but only recently surfaced publically on the F6 forum. Essentially it's quite difficult to get decent VO2max estimates for anything other than running or cycling. However, the Enduro and Fenix (probably FR945/745 too) will now calculate a Trail-specific VO2max estimate by adjusting the normal running VO2 estimate based on changes to the trail terrain as detected by the watch. Conceptually it's probably easiest to imagine this as being based on grade-adjusted pace (slope) with an extra adjustment factor for bumpiness/slipperiness (the reality may, or may not, involve machine learning...probably not). I'm not exactly sure 'bumpiness' the latter will be determined by the accelerometers but I'm sure someone at Firstbeat has given a good crack at it. Will it be super-accurate? Probably not but I bet the modified algorithm will be better for Trail than just simply using the standard running calculation. Time will tell. then the more you think about it the more this sounds like a running power calculation. Strange that. 3. new Rest Timer - you might all want to do some digging there as well. Maybe? Perhaps? (You do!)
