105-106% of Max Heart Rate?

[ric_stern/RST]

max heart rate is useless, why do so many people base their training on it?

base your zones on lactate threshold heart rate.

Maybe you'd like to take that up with British Cycling/Peter Keen?

To get a true maximum heart rate you can't rely on electronics - you have to measure it in a practical situation.
Read this:

then try one of the methods in this:

If you want a cycling specific max hr try the method here:

or just take 5-10 beats off your running max.

For the majority of us the true max hr is found by running.
This is detailed on many sites, here is an example.

There is evidence that people who have trained regularly all their lives have a higher max hr than those who haven't. The evidence that max hr decreases with fitness is not compelling.

So go measure your heart rate and use your hrm to train smart.

Great info - thanks.
