I borrowed my heart rate monitor from my co-worker again just to see where I'm at cardiovascularly. But before we talk about the data, a little backstory is helpful.
In December 2001, I was a junior in high school on the football team. I weighed around 165 at the time (about 185 at the start of the season) and my coach had told me that the next season I would need to be heavier in order to play offensive line on varsity. So I set out to gain weight. This decision became a long standing issue for my health that at the time I didn't realize the ramifications of. But by April (in 4 months) I had gained roughly 80 pounds. I went from a small 165 to a much larger 245. I had lost a lot of fitness gaining that weight. And at some point during the summer/fall football season (I can't remember when), I was having issues with my heart. Whenever we would run sprints to end practice my heart felt like it was going to explode. Under the advisement of family and coaches I went to see a heart specialist to make sure everything was alright. I ended up having an EKG and stress test. The stress test started with me standing on the treadmill not moving to get a baseline measurement. I was informed that when the test began I would continue to increase in pace until my HR reached the peak for the stress test. I was set to begin and then within 30 seconds of starting and barely above a walk, they stopped the test. I had reached my HR max for the stress test. I was shocked. While they didn't find any abnormalities, I was clearly way out of shape to be playing football safely. Although I did continue without issue. Fast forward 15 years later and I stand now a different man. My heart is much stronger. But putting in graphs instead of words makes it so much easier to understand. We'll get to that at the end. But why bring this story up? To help you understand that the data I'm about to show wasn't always like this. I've come a LONG way from where I was. So if you look at your own data and wonder why, just remember that this has taken years.
Thursday was another marathon tempo day. This time it wasn't blind. It didn't go as well as last week's run. But it was still comfortable. The big thing to note was the HR was 153. Why is that significant? Oh we'll get there...
Friday was an easy day. I pushed to go as slow as possible. For this day, it turned out to be a 10:00 min/mile. And with that came an astounding average HR of 126.
Saturday was an easy day, but an extended 10 miles. The pace was a solid 8:49 min/mile average. But the interesting thing comes from the HR data.

No HR drift. A solid average of 136 essentially from mile 1 through mile 10. It signifies a strong heart on an easy run when there's little to no cardiac drift.
Sunday was the first long run of significance. I went with 13 miles at a desired 8:13 min/mile. This was a VERY good day. I FINALLY felt comfortable running again. I was hopeful that taking the last two days really easy would help my body "catch up" and finally start to feel normal again. Mission accomplished. I ended up averaging a 8:01 min/mile, so a tad faster than I was suppose to. But it was a very comfortable 8:01 min/mile. Something I found very interesting was two-fold. First the ground contact time (the amount of time the foot spends on the ground). Less time on the ground = a more economical stride.

It's really interesting to see what I feel in real life. I typically feel natural after 4-6 miles of running. This goes to show that. Again the paces from beginning to end don't differ that much. But clearly the GCT improves over time. And the heart rate data is again important.

Again, 13 miles and beginning to end almost the identical HR with little to no change in pace (if anything it was faster at the end). A very strong showing. This run allowed me to know I was back. That if things continue to progress like this Dopey could be in big trouble.
Monday was another easy day but a serious attempt to try and keep my HR as low as possible. I didn't pay attention to the HR until after the run (I never look at HR until after it's finished). I nailed a very low 124 with a pace of 9:34.
Tuesday was the first HM strength workout (7:05 min/mile) going a total of 6 miles at pace with a total of 10.5 miles. I wasn't sure whether this pace would be too much for me, but I was ready to prove it. Oh boy did I! The splits were 7:05, 7:02, 7:03, 7:02! A very solid run. But the absolute shocking data was the HR. The first split was 157, the second 157, the third 154, and the last split 153. SO my HR actually dropped during the run?!?! Like what, what?!?!?

Incredible HR data and very helpful for the big picture. So from an individual standpoint the HR data helps, but I've found I can actually create a prediction calculator based on my personal HR data. So what does that look like?

Alright, this is a lot of data. What does it mean? The x-axis is pace. The y-axis is heart rate in bpm. The blue circle and blue line represent my HR from Jan 2015 to Apr 2015. The red triangle and red line is June 2015-Sep 2015 (during my first Hansons). And the yellow squares and black line is my current HR data. The lines are logarithmic curves of the data points.
What's important to remember about the blue line is that this wasn't when I started running. At this point in my running career I had been running for 2.5 years. A total of 2200 miles. I had completed 6 halfs and 4 marathons. This is to say, this HR data is not me just starting out. But astonishingly after/during once cycle of Hansons my HR dropped DRAMATICALLY. A HR of 146 was a 9:42 min/mile, then a 8:21 min/mile, and now a 8:01 min/mile. That's progress. So an interesting trend so what good can this serve? Well, I use the equation from the logarithmic curve to predict race times for different distances. I've found what my historical HR is during different races and then plug that value into the logarithmic equation to determine my current HR pace. In Fall 2015 I used this method to predict a 3:40 marathon (I ran a 3:38). In Spring 2016 I had one data point to predict a 3:30 marathon (I ran a 3:28). When I put in one data point from my current HR (about 4 weeks post marathon which would be the equal fitness point) I had a marathon prediction of 3:24 (I ran a 3:23:43 in October 2016). It's incredible how predictive it has been. So, the big question is what does the black line say now?

My mile time is predicted at 5:47.
My 5K is a 6:24 min/mile (19:50).
My 10K is a 6:43 min/mile (41:39).
My HM is a 6:57 min/mile (1:31:15).
My M is a 7:31 min/mile (3:17:02).
Now earlier I said it was important to note that my marathon tempo was 153, and now you see why. My historical average HR marathon average is 152.1. So my marathon tempo of 7:33 min/mile seems very close to appropriate. But this data is ever changing. If you look back at the HR data graph you can see a pink square. That pink square was today's run. So as you can see I am still improving (as would be expected).
Lastly, the other metric of VO2max. The last time I had HR data (Spring 2016) my VO2max was 55. Now, after today's run I got a new VO2max...

59!!!!
Now this isn't the end all be all. But it's another measure of fitness. Now I could tell you what the race predictor from Garmin says. But it's essentially worthless because it assumes you are ELITE. Only about 1% of runners actually achieve the race predictor times.
This is all to say that I am getting significantly stronger and recovering well from the October marathon and issues I was having.
