Have you read the Running Rewired book? I was looking at it recently because I really need help with my strength training but the reviews made me wonder if it would actually help.

@DopeyBadger, you might be interested in this. With my new Garmin Epix, I get more information on my training status than I've had before. I'm curious about what you think about it and how helpful you think it might be.
Garmin assigns each activity (all activities, not just runs) an "exercise load" number. From this article, http://runningwithrock.com/garmin-training-load/, this is based on HR, duration, and HR variability. These are used to estimate the EPOC (Excess Post-exercise Oxygen Consumption), and then Garmin puts all of this together into a number called the exercise load. Looking at some of the loads, they seem qualitatively reasonable compared to each other. I think Garmin may somewhat underestimate the load for tennis, though. Interestingly, the exercise loads for my three workouts this past week were all similar: the CV intervals on Tuesday were 173; the tempo ramps on Thursday were 168; and the 10.9-mi long run on trails on Sunday was 176.
Then Garmin sums the exercise loads for the activities over the last 7 days. This is what it calls the "acute load". As each day passes, the oldest day's activities are dropped and the current day's are added. OK, great.
The screenshot from my Garmin Connect shows the exercise loads by day in the top graph and the acute load over the last 4 weeks in the bottom graph. In the top graph, there are horizontal breaks in the bar, indicating that I did more than one activity that day, and they are stacked vertically.

Now comes the part that I'd like to understand better. The green band in the bottom graph is the "optimal range" for my acute load to be in, in order to keep improving my fitness. Where is Garmin getting this from? I've only had the Epix and been getting these stats since Christmas, and yet it computes this optimal range since I started using the Epix. I don't know how it could have any idea of my "optimal range" for training so quickly.
Regardless of the optimal range, I can see how the type of workouts/runs that are done will affect the training load and acute load. It's hard to see in the bottom graph above because it's stretched out so much horizontally, but when I started this training cycle (toward the beginning of January), my training load really ramped up, which made sense. However, the last three weeks are supposed to have been building - I increased mileage and time running, but the acute load graph has been pretty flat. So apparently I haven't increased my load as much as I thought I had. (?) Does that mean I'm not necessarily making training progress?
This upcoming week is a cut-back week, so it will be interesting to see how much the acute load decreases this week.
I can see much more starkly through these analyses how being limited to ~60-min runs on weekdays limits my exercise load and thus the possible increase in my acute load. Unfortunately, the need to work and have a life does exist.

I've written quite a bit on Training Load before. Start here:
Training Load
-A longer thread from earlier in 2018: The Beginner's Guide to Stravistix or How I Learned to Stop Worrying and Love the TRIMP (started by @kleph)
-An explantation of the terminology and whether "Fitness" = Pace: "Fitness" and "Fatigue"
-More isn't always better
-Finally figured out how to apply the mathematical formula of Stress Score, "Fitness" and "Fatigue"
Now the parts that will be more interesting.

Garmin's training load is much the same, but the numbers come out differently.
From my own personal experience, I suspect the Garmin has this information on the back-end all along and only "unlocks" once you purchase a device capable of doing it. It still won't show the data from the time period prior though. Based on the original research on training load, it should take about 42 days before the data is "true".
Don't get sucked into the mindset that training must always be going up for it to be optimal/right. There's a tolerance to how much training or building the body will take until you get diminished returns. I've found my timeframe is around 10-12 weeks or so. Garmin's displayed data is less nuanced than Elevate (the google plug-in for Strava) or Strava's "fitness". Ideally though, you want to see ebb and flow in your training plan just like you would in your yearly training cycles. Periods of high training and periods of low training. But training load can make it seem like the way to improve (or stay in optimal) is continuously building without the pull back weeks. Training load is better seen as a tool in the tool box that displays the following in simplistic terms:
"The training you are doing today is different enough from the last 42 days worth of training to make it ideal, but not too different from what you've been doing to make it an overload."
There's a window of different enough without being too different that the body likes to be in for making gains. Too little difference and you'll live in the neutral/stagnation zone. Too different and you'll overload.
One thing I found interesting about the Canova training in my last marathon cycle was that per my Garmin I was never in the optimal zone. The ramp rate of the 30 week training plan was so low it always saw me in the neutral/maintaining zone despite making very very slow gains.
While Garmin (and other devices) combine training load into a single value, there are some that believe the training load metric is best viewed within individual sports rather than solely as a combined value.
Lastly, keep in mind that the accuracy of this value is solely dependent on the accuracy of your inputs. So if your HR zones are off, then the data is off. If you get bad HR data on a run, then the data is off.

!!!Today was 1000 days in a row of me getting at least 10,000 steps!
Somehow I didn't see that you had posted. For the majority of the time, doing something else, especially something active, is a huge distraction from the headache pain. Running, walking, tennis, and teaching class are usually something that I focus on enough to be able to background the pain - there are other physical sensations going on or something I'm really mentally focused on. But then other things are NOT distracting: grading, other computer sorts of work, reading, etc. That's when the headache pain just really drags on me and makes me tired and depressed.I don't know how you are functioning with these ongoing headaches. I am very impressed with your ability to do the work you do, and also keeping up with your exercise routine, through it all.
Thanks! Trail running is definitely a whole different type of running. I'm happy with how I've progressed with it.I'm always impressed by your trail runs! I don't run them often because I don't like driving to go run but anytime I do, I'm surprised by how much more difficult it is to my paved paths.
Regarding snakes, last time that I saw a snake on my run was the last time I ran that route![]()
