Time for a speed test

I had been planning to make an attempt at a new 10K time this weekend. My plan was to go out on Saturday morning and see if I couldn't take at least a minute, and possibly a minute and a half, or even 2 minutes off of my current time. That's kind of ambitious, but I do feel that I have been gaining speed recently, and it has been 2 months since I last made a serious try at a 10K training PR.

As it turns out, it is supposed to dump rain on Saturday morning. I don't feel like trying to set a PR in heavy December rain. The rain is supposed to at least slow down by the afternoon, but this is the afternoon of Christmas Eve, and I would rather be at home, or picking up last-minute stocking stuffers.

So I have decided that I will run tomorrow (Friday) instead. Friday is usually a day off, but as I will be taking Saturday and Sunday off (Sunday being Christmas) I might as well run Friday. I will see if I can run at a sub 4:20 pace for the last 5K of a 10K run. There is quite a bit of downhill in those 5K, so it should not be too difficult, but at the same time I might get a new 5K PR.

--------Update-----------
Got the new PR in 20:59.7, which is really squeaking under, but it counts as a 5K time that starts with a two and a zero, and it's faster than I was expecting to get. Of course, there was 66 meters of elevation loss and though the stops at traffic lights did slow me down, they also gave me time to catch my breath. But considering I had run 45 km in previous three days, most of which was fast, I'm guessing I could repeat it on a flat course with taper.
