If it isn't measured...does it count?

Well, last week wasn't so good in the training department...and it was the first week too!
The hubby, Charlie and I head out for 3 day sail to Portland Island and I had brought my stuff to measure my walks, but of course didn't use them.
Portland Island is a Marine/Island Park here in the South Gulf Island off Vancouver Island. There is a great 10 km trail around the island that is rather technical (to use the term loosely) at times. We hiked one day of 4 km, then the second day we did the full 10 in 2 1/2 hours and then the third day we did another 4 km hike. For a total of 18 kms and with the measured 10 km I have posted that is 28 kms for the week.
I see that is in step with the prescribed distance we have set for this week. Then why do I feel like I didn't get my training in?
It used to be that if I didn't bring my watch and time all my runs it seemed to not count and now with the nike + system, it seems worse! I need to see the km posted on my sight to think they count as training. What did we do in the old days? Oh yeah...we headed out and did the same training and didn't think of times/ splits/ distances so much.
Maybe I've become too entrenched in the computer age of measuring distances, times, splits, averages and the sorts. So...now looking back at the week....I did get my training in....you'll just have to take my word for it!
