After all, even though you're 63yrs of age, you're putting in more than 60% greater mileage, and you're working harder at it. It wouldn't be a surprise to see some of the changes you've been having. Lower resting HR, lower max HR at a given level of effort (even higher effort), faster times, greater power and strength, improved recovery ability, etc.

Lucky you!


Given your age, definitely bring up these things at your next appointment with your general doctor. We do generally slow down as we age, in terms of our cardiovascular systems. But I don't imagine it's much to worry about. Some of it's probably age-related slowing; though the training you've been doing probably explains the rest of the "positive" gains.

Time to re-do those mileage/heartrate charts and expectations. I bet everyone wishes for such a problem.
