Suddenly Slower???

ha, i don't even pay attention to my HR...

The problem with using heart rate as a guide is that it's too easily affected by things that have nothing to do with changes in your fitness. That doesn't mean that you it's useless but you have to be aware that it can change based on time of day, heat, humidity, hydration level, how you slept the night before etc.

Another possibility is the elevation. Most of the east is too low to have much impact but parts of the North Carolina mountains are high enough so that you could feel some effect if you're coming from sea level.

Are your prs slow enough for you to be training this slowly? What are your prs?

This was after returning back here to Florida after 1 week at North Carolina. Plus my heart rate has been consistently at 140-145 on easy days at 9:20ish pace.

all of a sudden I can't get it under 150 without slowing down to over 10:00 pace. Why???

PRs:

1600M: 4:59

5K: 18:24

Plus that is my easy day, not my aerobic pace (7:30-7:50ish pace).

I'm following HADD's training (which has been working btw) but I'm just wondering why my HR is suddenly way too high for my paces???

Stop worrying so much. If you feel tired, take a day off and get some extra sleep. Really, you are making this way more complicated than it needs to be. Summer training is easy. Also, you can probably stand to pick the pace up to at least around 8:30 or so. There is no reason to be running that slow.

Again it could be a lot of things. If you feel OK on your runs I wouldn't worry about it. If you feel bad then maybe you need to get some things checked out. Assuming that you've ruled out the obvious things I mentioned earlier it could be a low level infection or low ferritin. Are you by any chance a teenaged girl? Iron issues are pretty common for young female runners for example.

Probably not iron then unless you're a vegan or something. Could be a bug of some type. I had a few weeks of bad workouts 1 year for no obvious reason then came down with a fever and swollen glands. Turned out that I had mono.

Bump..

Anymore ideas?

Do you actually feel tired and/or slow, or are you bagging runs purely because your HR is a little higher? In all seriousness, take a day off, sleep in, and I bet you feel fine.

Well, I felt pretty normal (aside from tendon) when I ran. I guess I'll just run 30 min in the morning with my XC team and take the afternoon off, with lots of "painful" icing for my tendon

If you are not feeling tired then maybe your HR monitor is malfunctioning.

Nope, I took my pulse too, it was correct

I also noticed something else. Whenever I lay down for 5-10 min, my resting HR remains at 44-45.

If I take my HR standing up (this week) it'll jump to low 70s and it won't go below 70. What gives???? (could be a clue?)

Normally when I stand after laying down for 5-10 min, my HR will go to low 60s, then around 30 secs it'll be in the low 50s (52-53). Yesterday, before my disaster of a run, my HR when standing up was 72-75. Felt funny feeling in my chest.

Any ideas???

^This. You are probably tired, or underhydrated, or have a touch of a bug. I think you're overthinking this, and it's making you anxious, and that doesn't help your heart rate.

However, I'd be more concerned about running so slowly. When my son was 17, he did his long runs (13 miles) at a 7:00 pace,and this was realatively easy for him. Shorter runs were sub 7:00. You need to work on picking it up.

Ditch the HR monitor for awhile, and run by feel. I think you will be fine.

What's the benefit of running 9:50 pace anyway? When I was running 18:30/4:59, anything slower than 8 min/mile pace was just plain irritating.

A few thoughts...

First - running in the hottest part of day with high humidity will cause the HR to soar versus cooler temps. If you're running in higher temps/humidity than you were before, this may explain most of it.

No, you didn't lose all that fitness. You lost a little. It will likely return shortly if you continue running.

Yes, taking a week mostly off will typically make my pace slower for the same HR. I used to take 2 days off every 4 weeks, as a stepback week, and the first day or two back my HR was noticeably higher for the same pace. But, within a few days back running it would return to normal. That was after only 2 days. You took a week mostly off.

This will probably be even more pronounced in your situation since you're running fewer miles, and have a smaller base (less miles, and only been building it this way for 8 weeks).

You sound like you're freaking out. Don't freak out. As long as you feel ok, stick with the program and it will come around.

Wait to continue your new program when you get back home.

Stop running and walking hills for now. Obviously you are straining your achilles. It's the sudden introduction of hills as you have surmised.

The HRM is a feedback tool. It may or may not be everyone's tool of choice but it is telling you something.
