Subject: Bought a HRM...now have more questions
So, the other day, I bought a polar S-120 from trisports. I'll have to admit, a fun little toy but not sure how to use it to it's potential yet.

The last couple of days, I've been trying to figure out my MHR and how to use it based on the write ups in the articles section.

My questions are:

1) Just say you are training at 50% of your MHR and just say mentally, you are like, "I just can't sustain the 50%." Are you suppose to just keep trying to train at that % because physically you can sustain it, because it's only 50% of your MHR?

2) I guess sort of related to #1 above, is there a general chart which shows how long you are suppose to train at a specific percentage?

For example, if I train at 50% my MHR, am I suppose to maintain it for 20 miles? If I train at 75%, am I suppose to maintain it for 10 miles?

2) What percentage of your MHR are you suppose to race at?

Are you saying that 50% is too fast for your to maintain?

A full training program progresses through over several months. Typically you'd be doing 2-3 months of aerobic only training...around 70% of your HR max. Eventually you've built a solid base and you can add some more intense sessions in higher zones...tempo work. The final addition is interval work where you can be 90% + of your HR max. As for racing, it really depends on the length of the race. If you're going to be racing for an hour+ then you should really stay in your aerobic zone for most of the time, ramping up as you close in on the end. I just ran a 10K today where I held a steady mid Z4 (85-92%) for the entire race and then built up to Z5 (98%) over the last mile or so. That took some serious mental effort to hold Z4 but it isn't unreasonable and since I finished in a little under 37 min I really didn't have to hold the pace that long.

Some recent threads about HR training to get you started:
