No workout log...

Evidently, you are all updating your workout logs.

I stopped logging years ago. It is't as vital as many believe. Just run baby.

Running logs are interesting. About 3 years ago, I was addicted to recording every detail about my run. Min HR, max HR, avg HR, altitude, pace -- the whole works. I'd even race with my Polar watch and footpod on. Eventually, my watch quit working and was out of warranty, so I just quit recording everything. And surprise surprise, I kept improving and PR'ing.

Having said that, I recently went back to my logs and found the information interesting, sort of like a personal journal of what life was like back then. So I'm creating a new running log for myself and will begin recording stats again -- not to over-analyze and tweak every run, but simply to keep a record that I can look back upon and see how my physiology has changed with time.

In addition to that, I think logs can be valuable in that if you have a season where you improved a ton, you can look back and see what you did differently from before and continue doing that.

Similarly, if you get injured or burn out, again you can look back and see what caused it, or look at your morning heart rate progression to see if you were overtraining. As a college student, I am particularly interested in the effects of sleep, and having the ability to plot this versus performance will provide some valuable insight for me.

But no, I no longer finish a workout and obsess over the pace, the mileage to the 2nd decimal place, or if my heart rate was 3 bpm too high. I don't schedule my mileage anymore for a particular day weeks in advance, because I can't possibly know how I will feel then. I'm sure this concept is intuitive to most, but surprisingly it wasn't for me until I graduated from high school.
