Today was my first post-vacation 10K, coming nine days after the last one, when it was 30ºC. It was also my first run since this Thursday when it was even hotter at 33ºC. The weather has changed and I’m reasonably confident the last hot days of summer are over. With the sky overcast and the temperature a mere 17ºC (which is, in fact, almost ideal for summer running and is perfectly fine even if you’re strolling out and aboot), I set out this morning to find out just how much of a difference 16ºC could make.

As it turns out, a lot!

My pace last Friday was a molasses-like 6:01/km, one of the few times I’ve slipped past the six minute mark. I was not impressed. I was sad. I felt old. And slow. And sweaty. I remember struggling to pull my shirt off I was so sweaty, like the start of some porn scene gone horribly wrong.

Today I decided to start exactly at the 0 km marker and run the exact, official Burnaby Lake Loop, to see how well the markers matched the GPS. When I strode past the 10 km marker the watch showed me at 9.88 km–pretty close, really.

And when I passed that 10 km marker I was not bathed in sweat. I actually only sweated a little, mostly in my favorite spot, which is around the sides of my temple. Why these spots generate so much sweat I do not know. Maybe my brain is mentally jogging at the same time. My pace turned out to be 5:28/km, not only handily eclipsing the previous 10K but also besting my fastest 10K post-injury, which was 5:41/km.

The only downside is the right hip area started to feel a little sore when I applied thrusters. Moderating my pace corrected this, though it still feels a little sore tonight and I suspect it may be a bit stiff tomorrow. I’m not overly concerned as it feels sore rather than hurt.

Given the cooler conditions there weren’t as many people out but still more than I expected. There were a lot of runners, including more cute young male runners than I am used to seeing. I only point this out because almost all runners I see, male or female, tend to be in their 30s or older. I didn’t recognize most of these runners (I see a few regulars most days) and one of the young guys was absolutely drenched with sweat, as if he was in a bubble where it was still 33ºC.

Other than the small degree of soreness in my right leg, the run went very well. For the first time in a long time I actually felt a second wind on the back half and my pace picked up after the usual midway drop. It was nice.

Tuesday’s forecast is currently calling for around 21º about the time I am running, which is warmer but still much cooler and the rest of the week looks like poop from a summer weather perspective, with a chance of rain and highs in the upper teens. I’m liking the temperatures but could do without the rain. I’ll take the rain (to quote R.E.M.) over more 30ºC+ temperatures, though.
