It is common knowledge that the better shape a person is in - the lower their heart rate is at rest, and, I think, the lower their heart rate is for a given speed when running.
I would like to know:
- Is there a standard indicator to express the relation between one's heart rate and their running speed? (e.g.
BPM/mph
). - If so, are there standard tables or graphs that provide the normal/desired values per age group / gender?
