Since I bought the 955, I've put a fair degree of effort in my runs, increasing my acute load by quite an amount by doing some zone 2 and speedwork. Quite a number of my activities have been listed as VO2Max being the primary benefit.
I'd expect my VO2Max to increase as a consequence, but it's been flatlined since the end of June.
Am I doing something wrong, or is the watch/Garmin? I know I shouldn't really be that bothered by the score as it's not all that reliable in comparison to lab testing, but I'd still like a bit of reward for my efforts...!
