Ive been cycling for quite some time now averaging 220 FTP however just started running 5k in just under 40 mins , I am 48 97kg but looking at my Vo2 max apparently i am 20 years old.
Any suggestions or a way to reset this to start from scratch.
I just bought a forrunner 935 upgrading from a Vivoactive 3 if that makes any different and use a Garmin 1030 , power meter and HR strap when on the bike.
