I am 51, completed 15 tri's, looking at a 1/2 Ironman next. I am not very fast but I pace extremely well.
Now matter what I do my heart rate is 180-200. I don't feel uncomfortable, and I work out for hours. Esp. on runs. Anybody have info on this?
I am 27 years old and experience the same thing, sometimes I even see it spike to 220-230. I've had stress tests and talked to cardiologists about it and they have no answers and say I'm in great shape. I don't know what to do. Have you ever experience a problem with you heart beyond the numbers?
I have never had any trouble, was totally surprised.
I have learned that heart rate vary widely. Not only is it the pressure of the blood but the size of the arteries and veins. I have done over a dozen tri's and I am training for a Ironman. Just started training by zones and was concerned.. I'll take my BP and other stats at work today.. Henry
Forget about heart rates in absolute numbers. The number that counts is the percentage of your maximum heart rate (HRmax). Note that HRmax is different for cycling and running. The simplest test to find you HRmax is to run/cycle full out for 1-2 minutes and get the max.
CAUTION. THIS METHOD IS NOT RECOMMENDED FOR BEGINNERS!
Then train on 60-70% of that for endurance, about 75% to increase lacate threshhold, and 85% for speed.
Around 75% would probably also be a good race-pace for a longer distance.
