I'm getting back into my cardio routine, after sometime off from running. Previously I was a strong distance runner, but am now getting into cycling for my cardio. I noticed today, using my Polar HRM, that my average heart rate was about 168bpm, for a 5mile ride that only lasted about 30min. Oddly, my breathing was only at about 50%, no fatigue or laboring. I could have went at this pace for quite some time.

My question is, is this a sign of lacking cardio performance? I just found it odd that my heart rate would be that high, and my breathing be so low with no fatigue or trouble. Any advice on what this may indicate would be most appreciated. Thanks in advance.
 
no. It is pretty standard. That rate is only in the moderate level (depending on your age and MHR). If you do some increased deep breathing it will probably lower a bit.
 
i would think great muscle performance, and a lacking cardiovascular system??? but i definatly could be wrong...
