Effective use of HR(2 posts)

Effective use of HRmanicoti

I am relatively new to riding fast and have gotten a Polar A-3 and Cateye Astrale to aid in my training. How do I find my zones and LT with only these instruments? I've read Friel's book and need help.

One of the methods Friel describes for finding LT is to do a time trial at an all out effort, noting your heart rate for the last half. That is close to your LT.

Here's a description from trainingbible.com:

Long warm-up. Then ride a 30 minute time trial all out. Race effort. Use a flat, out and back course. 10 minutes into the time trial punch the lap button on your heart rate monitor. Afterwards, record your average heart rate for the last 20 minutes. Also record distance covered or average speed.

If you don't have a lap button, just note the figure. It should remain pretty steady, increasing only slightly over time.

The HR over the last 20 minutes is, I think Friel says in the early chapters, about 5-10 beats above your LT.

Good luck,

Bryan
