On my way to India today. On a whim, I did a 1/2Monty in the AM before departure. I’ve been training more than most years, but am now 63yo and haven’t retested in about a year (trauma of the Full Frontal just made me avoid testing altogether for a while).
And so… my numbers are officially down - from max heart rate, cTHR to ftp (though oddly, a 3% bump up in MAP). Garmin has been steadily dropping my VO2 number over the past 7 months just to salt the wound. I’ve commented on this before - about how these numbers shouldn’t matter so much. My consolation prize is that I’m still tip-top “given my age.”
Nonetheless, it’s not fun when you’re finally on the receiving end of the inevitable decline
