Weird heart rate observation(6 posts)

Weird heart rate observationBiking Viking

I do a long endurance ride every Wednesday morning before work. During the winter I sometimes combined that with some steep climbing to build power.

This Wednesday I went all out and did a ride that a local bicycle club here in the SF Bay Area has named "Sheer Gluttony". For those familiar with the area, it combines Redwood Gulch, Bohlman, On Orbit, Tollgate and Montebello in one ride. It's 52 miles and over 6,500 of elev gain - some of it at up to 22-degree gradients.

This is much harder than I usually ride on a Wednesday, but I rode directly to the office and felt good, except that a huge endorphine rush, which lasted well into the afternoon, made it difficult to focus on work. Riding home, I felt strong, but wisely resisted any urge to hammer. I went to bed very energized, got up the next morning and felt great - it didn't even feel as if I'd ridden the day before.

I rode to work the next day, still feeling OK and decided to go for a lunch ride since the weather was so nice. I went for an easy spin and felt really, really good, but --

My heart rate was ridiculously low throughout the whole ride, 15-20 beats under normal. I tried to push a little up one small hill and it wouldn't even move. Everything felt normal, but looking at my HRM I could tell something was wrong.

My question is: Is this normal and what causes it?

Don't know the answer to your question, but I'd be making a phone call to my doctor.
How are things today with respect to energy and heart rate response?

I didn't go for a lunch ride today so I don't know about the heart rate. I rode to work this morning (without my HRM on) and felt very energized. Everything feels normal.

Somewhat normal...brider

if the rate is constant. If it's erratic, then yes, I'd say see a doc. You're just not recovered. Take a couple easy days, then test it again. If you persist in trying to push it, you'd be in full-blown overtraining. I know when I had my best 40K TT time, my heart rate never got over 155. Of course, that also the day after the district hillclimb TT. Similar to what you're seeing now.
That's my guess too, but...Biking Viking

...I'd thought I'd feel tired if I wasn't completely recovered.

On the other hand, I have noticed that on interval training, my heart is much more "responsive" if I haven't ridden much in the previous days.

usually when your HR is lower than normal and you are struggling to get it into the range you are shooting for its due to overtraining....just cause you feel fine doesnt mean your not overtrained...take some time off and see how it goes....either that or you just increased your VO2 max in one single 53 miles ride =) not likely tho =)
stay stoked
