It’s not the heat, it’s the humidity run

Distance: 11.29 km
Weather: Overcast, light drizzle
Temp: 19ºC
Wind: none
Calories burned: 789
Average pace: 5:10/km
Total distance to date: 901 km

Today I completed the third part of my Burnaby Lake loop trilogy after a couple of days’ rest and achieved two new milestones (or kilometerstones as we call them in Canada):

  • I officially passed 900 km on the Nike+
  • Had my longest run to date at 11.29 km

The conditions were a fair bit different for today’s run vs. that of Thursday. To wit:

  • I ran in the early afternoon (1 p.m.) instead of the evening
  • I ran on only one meal instead of three
  • There was absolutely no wind at all
  • It was extremely humid
  • The slugs had mysteriously vanished
  • I ran past a horse

The run was much harder than the previous one and at times I really felt myself laboring to continue but I pressed on and even ran an extra (but short) leg just to make sure it would be my longest run to date, if not the quickest.

I still finished the 10K portion with a second best-ever pace of 5:09/km and an overall pace of 5:10 (or 5:11 depending on which part of Nike+ you believe), so my performance was still good despite the struggle. My shins are feeling a bit tender now but I am unsure if it’s due to the intensity of the runs or if they’re getting hurt. I’ll know better tomorrow on my day off.

One of the important things here, I think, is to not run after just a single meal (breakfast). After the run my caloric intake for the day is actually negative as I burn off all the calories from breakfast and then some. This would be handy if I was trying to lose weight, but I’m not. I’ll also keep in mind the conditions at Burnaby Lake for future runs there. There was a heavy rain yesterday and today the air was thick, warm and heavy — very unappealing for a run. I sweated not unlike the proverbial pig.

Interestingly, I had a rare instance of my second km being faster than my first. No idea how that happened.
