Another 7 miler under my belt today @ 4:03 min/k (6:31 min/ml). I started at my usual sub 4 min/k but the legs started filling up after only 4k. When I reached the 7k mark I had slown down to 4:07 min/k which is the pace I should be running anyway. I managed to speed up a little over the last 3k but it wasn't easy. Average HR was 83% but I am not sure if my HRmax is still correct these days. I shouldn't be able to run daily at 80%+ HRmax, should I? Maybe I have to put that to a test at some point (any ideas on how to do this in the field are more than welcome as it is obviously a well kept secret how to get a clinical test done in Tokyo).
Today felt somehow as if I am approaching a certain limit. At least I know I won't be able to pull the sub 4 min/k runs next week like I did in the first one (after a two week taper for a marathon I ended up not running). Maybe the lack of sleep, again too many beers last night, two hours less recovery in my 24h running cycle or the heavy Kayanos played a role today. Not sure what it was but I ran 90 seconds slower on my weekend course than last week and I didn't do it voluntarily.

I think it is due to old age ;-)
Man, that would suck. I thought we runners get better in our mid 30s... maybe it's time to really get started with these green tea cucumber masks. I heard they stop the decay and even make you run a new 5k PB!
