Last Sunday's run was the start of what is turning into a tough week. That run was scheduled to be a half-marathon race. Given that the week before I pulled a 2h05ish time for that distance, I thought I'd just have a "reasonable" pace for 2hrs and call it even. But not wanting to do the same route again, I chose to do trails near my house for a change of scenery. Those trails were made up of long, drawn out hills that sapped me and left me with an HR that was typically at or about 85% for the full run. After that, I decided to pay close attention to my HR again during my training runs and make sure I wasn't falling into the "junk mile" territory like I usually do.
I was strict on my shorter run on Tuesday, following the intensity guidelines to a 'T'. Wednesday was a bit different though. I was unable to do the run intervals, so I did bike intervals to "make it up." I pulled out Spinervals 9.0 - it's titled "Have Mercy" - and did 30min of kick-yer-ass-hard intervals. I wanted to give 'er to make up for the run, and I sure did. After those 30min, I could barely climb the stairs, and I felt crappy after (still do).
Today that continued. The plan called for a rest day, but I decided to get to the swim tonight since I missed it on Tuesday. The warmup was 4 x 200 all strokes - an indicator that we'd have our asses handed to us again. 12 x 50 mixed strokes with fins was next, and each 50 was prefixed with a 10sec flutter kick with arms out of the water (aka tough). Then it was swim/IM sets. I did my best all the way through, and it kicked my ass. Adding to the fatigue was the fact that I just couldn't get my timing in butterfly today, so I worked 2x as hard on that stroke all night.
One thing that has stuck all week is that the harder intensities leave me feeling "head-y" and my HR has been quick to jump up high too. Am I overtraining? Am I holding intensities too high for too long? Is this just an off week? Am I catching a cold or something? Is this normal fatigue for the point I'm at in training?
Too many questions again, and no answers yet. For an engineer, that's torture. :D
All of this is scaring me into thinking that there's something with the heart going on that I can't detect. I know I've had a couple of "blips" in the morning after I wake up, but I haven't felt anything through the rest of the day. I've had a wee bit of vertigo on the bus commute, but it's gone away. I'm tired, but I always am (I've always wished for a couple more hours of sleep - but I think that's common).
So what does all this mean? Well, I think it's safe to say that marathon training doesn't do much for high-intensity efforts. And it doesn't do much for cycling. Or swimming. And since I don't do those as much as I used to, it's probably just naturally harder right now. But then there's the other side of thought - if I were doing an Ironman, I'd be doing all three, so just shut-up and HTFU. :D
I'm sleepy, so I will do the latter for now. Hopefully this all washes away with a good sleep and warm shower. The test might be the run intervals tomorrow. Not a lot, but still tough - 6 x 75sec at 100% effort. Bring it!
Well, bring it after a good night's sleep. :D
