Bike Ride - did I ride this too hard?

By definition, its would probably be impossible to spend that much time in Z4 and Z5; I would go back and determine your zones again.  If you felt great afterwards, and you still aren't suffering now, you're probably fine.

edit: Every now and then my 305 gives me a funky HR reading (based on my RPE.)  When I upload the data to Garmin Connect it appears that there are lots of spikes into the 250-ish BPM range.  You may have something similar skewing your data.

My Garmin soft-strap showed my HR up to 250 and sometime in the 200's for over an hour.

I am now using a Polar Softstrap with my Garmin ANT+ sensor and had not any issues.

I think the HR-strap from Garmin might be causing reading issues in your case as well.

Further, you may want to elaborate on how your HR zones are defined.

There are multiple options in doing so, some better, some worse...

x2.  Also lets say your HR zone 3 is 150-160 bpm and zone 4 161-170.  If you are riding around at 161 technically you might be in zone 4, but in reality you arent doing significantly more work then having a HR of 160 and being in zone 3

Makes sense.  You've probably nailed it here.  I need to do another Lactate Threshold test and see what my HR's are now.

I don't really think my HRs were skewed/spiked.  I have very few problems in this regard with my 910.  And on my previous 305 for that matter.

You probably need to retest your zones.

If you finish a ride feeling fine...there is no way you rode too hard.  If anything, you didn't ride hard enough...just sayin. 

I don't know anything about HR zones.  The answer is no.

So is that "awesome for a 60 year old" or just awesome in general?  
Kidding!  Thanks.

This.

You mentioned you were a runner.  Have you done HR training in the past and know what your running zones are?  Generally cycling HR zones will be about 10 bpm less.

Here are my riding and running Zones based on LT testing I did last July/August.  Looks like about 13 bpm difference or so.  (And yes, my max. HR is pretty low relative to many other people.  183 is the highest I've ever recorded - at the end of my 5K PR.)

?

Those numbers are remarkably close to mine.  FWIW, I'm 59 and have a resting HR of 41 bpm. 

I find that I have to put out a fairly reasonable effort to stay in Z2/Z3 on the bike when I'm riding on my own. I usually don't get into Z4 unless I'm doing intervals.

What is it about riding in lower zones that helps build endurance, as you say, that riding in the higher zones does not?

Thanks for the response.  I guess what I'm having a hard time understanding is why you would suggest that there is a greater training benefit to the OP by riding easier rather than riding harder.  He said he felt good, was able to run long the next day - I guess I just don't understand the suggestion to take it easier.

Well, the thread was about cycling, not running if you want to stay on topic. So scratch item b (though I would agree with it). None of the other items make sense or are really blown out of proportion in importance. Training at threshold is still highly dominated by the aerobic part. Perhaps I'm missing something from the context of where this was taken from.

I don't think you're missing anything.  I agree completely.

To the OP, sounds like you did not ride too hard since you felt good and were able to run fine during your next workout.  Unless cumulative fatigue were to begin to build by riding at that effort, keep it up or ride even harder. 

As an aside, riding in Z1 would be a waste of time for most triathletes at almost any time of year (unless it is a recovery period after a harder interval).  Few ride enough where Z1 will be very effective in driving adaptations.
