Subject: Racing HR Questions
I've done my first two months of HR training and am racing a duathlon tomorrow, 5k run, 30k bike, 5k run. I expect it to take about two hours. I've been using the max heart rate calculations. During the race, what zone or percentage should I be in? HR racers, do you deliberately back off if your HR spikes? Do you push it up a hill? Before my HRM, I used to train by going hard every time out, so this is new territory for me. I want to use the machine without being a slave to it.

Any advice or experience would be helpful. It would be great to know what to expect, so I don't get shocked tomorrow.

Since it is a realtively short race, I would run the first 5K at your upper threshold, and then hammer the Bike and the 2nd run

Anything above 1h, I always stay in Z2 for the first 20-30mns. I find that If I don't do that, my finish goes to pot. Based on this, I would do my first 5k in Z2 and possibly the first 10mns of the bike leg as well, then move up into the 80-90% range. Bear in mind that your lactic build up above 75% shoots up and goes the roof. The earlier you get to it, the quicker your legs will get saturated. I can't hold the 90-100% of HR as an average for more than 40mns (10k race).

Isn't Z2 the 80-90% range?

Depending on your level of fitness it will vary.

Opinion #1 take off the HR monitor when you race. Go by feel alone and learn your body the right way. Putting limits on your HR while racing limits your true racing potential.

Opintion #2. HR Monitor is a great tool used for training only....keeps you from going nuts every time out.....Use it properly and your fitness will imporve.

It is too late/early for UK guys like me to think straight. I meant Zone 1 (if 65-75% is what you guys call it).

I wore the HRM, mainly to find out how the ticker behaves under the circumstances. I checked it now and then, although my focus was on finding a good rhythm for cadence and breathing. The breathing was more frequent than most training, as I was in a higher zone the whole time, but during each leg, but once I found a rhythm, I was able to settle in and push myself some.

Using the Max HR method, z2 is 70-75%, and z1 is 60-70%. I spent the whole two hours between 85-90%, which felt good, although I understand you can't do this for a longer event.
