Anyway, the serious dehydration and lack of sleep might explain the lack of progress in today's run. Which is a waste because I took some extra resting days so I would be fit and could break the 4k barrier.
Today's run intervals lasted 3 minutes each, a bit shorter than last run. So I figured I could speed up a bit and get the 4k with some nice speed digits. It felt I ran faster then usual but my Nike+ stats tell a different story...
Actually, the stats don't tell that much unfortunately. I like the Nike+ but the graphs are really limited. The data is there, so I don't really get why the graphs are so limited. I guess I need to go and see if I can access that data and do some graphing myself!
