Do you take rest days? An elevation in heart rate like you're describing can be one sign of overtraining. But I agree with the previous poster that if it continues (even with proper rest), it's something to discuss with your doctor.

I think you should check with a doctor on this.

I'm a runner that runs between 20 and 30 miles per week. Normally, I'm able to run a pace that keeps my heart rate between 130-140 beats per minute. If I do that, I can run as long as I want. However, for the last 2 weeks I've had an issue keeping my heart rate that low. Seems that no matter how much I slow my pace, my heart rate climbs into the 150's very early in my run. I've had no change in my diet, sleep, or health. Don't understand what's going on. Any ideas?
