The spreadsheet allows you to enter your lactate thresghold for each of cycling and running and it calculates the zones for each.
You do have to determine what your lactate threshold level is. TrainingPeaks and other site can show how to do that with a field test. The rule of thumb is about 7-10 beats difference. The example in the spreadsheet was 15. So it is fairly individual.

I train both the same. The bike is usually 10 bpm less than the run, so I just work a little harder on the bike.

My difference is closer to 20....I guess it varies a LOT from one guy to the next.

I use different HR for biking and running. I used the formula from the book _Be IronFit_, and the author uses a different percentage for biking and running. Can't remember the formulas off the top of my head though.

Generally your run HR is 10bpm (give or take a few) higher. Some accomplished cyclists will have a max heart rate on the bike the same as or even greater than their run max. Its due to the amount of muscles you use in running. Interestingly your swim heart rates are always high. I'm not sure, but I think its due to holding your breath.

Interesting that everyone has a different method.
I did the 30 minute run test (30 mins hard, record the last 20 mins) and I got an average of 179bpm. The funny thing is I didn't even feel any real burn, just lung fatigue, probably from the cold air. I think I'll repeat the test in a month and do a full-out 10k and see how the numbers differ.
As for the bike numbers, I think I'll test those separately and get real data instead of guessing...it seems to make more sense.
Thanks for the info everyone

I'm sure this keeps coming up, but I keep forgetting what is said so I'll ask again.
When you're all training, do you use the same heart rates to gauge your exertion on bike as you do on the run? I mean, if your Zone 2 work is 135-145 on the run, do you use the same numbers on the bike?
I've heard that you should take about 10bpm off your running HR to get your zones for the bike because the bike uses fewer muscles (basically only your legs are working so if your HR is still 145 then you are pushing your legs too hard).
It seems like some people use the same numbers and other adjust. What do you all do?
