Hi, Welcome back.
I hate to rain on your parade but your pup sounds too young to be getting such vigorous exercise.
It should be average of 5mins per month of age, a couple of times per day.
Bike rides and hiking may be too much.
Why ??
She will happily do all of that and moree if you let her however. . .
Too much exercise at a young age can lead to early hip and joint problems.
Years ahead of when you would expect to start seeing it.
Because you are stressing the joints and bones while they are still growing and forming.
This sort of exercise shouldn't really be happening until at least a year old.
As a pup she's going to be running around at home and in the garden etc.
I'm not trying to ruin yours and your pups fun, just trying to safeguard her good health into old age.
