Probably normal: As the hr increases with exercise, it is expected that most people will be aware of it. This is not a problem. However, while exercising, if you suddenly become aware of a unusually rapid heart beat (as is a switch was suddenly turned on), the that should be checked out. A treadmill stress test or a monitor worn while exercising would provide the answer. These are usually not life-threatening.
