Does your doctor know you are a runner?
A resting heart rate of 60-70 is good or normal for a non-athletic person, but many physically fit, active people have heart rates in the 50s and even 40s, and that is considered normal and healthy for them.
I'm a runner as well, and my resting heart rate is 53.
ETA I found this:
"The most common and best reason to have a slow heart rate is to be physically fit. If you exercise more, your heart can supply your body when it is at rest with fewer beats per minute. High-performance athletes often have heart rates in the 40s. There is essentially no heart rate that is too slow—as long as your body is getting all the blood it needs." health.msn.com/health-topics/heart-and-car
