I have mapped out a little 6km walk and have been doing that early every morning. "Early" means I usually start at about 5.50am. Never in my life would I have imagined I'd be doing such a thing. We're on daylight saving time here so the sun's not up some days and it's barely even light. I usually walk out my front door thinking, "Really? This is what I do now?" ;)
It's a walk with a few small hills - two are a short, sharp incline and two are a long, steady incline - and the rest is mostly flat. I usually do the walk in 70 minutes, meaning my average speed is (obviously) just under 6km/h. In the past few days I've been working on getting my time down - goal is to do the walk in 60 minutes or less, so I know my average speed is 6km/h or faster. Yesterday I managed to get it down to 67 minutes, which was the first time I'd been under 70 minutes. Yay! And today... today I did it in 63 minutes. How did I manage such a feat? Partly by walking faster, and partly by jogging bits of it.* Jogging. IN PUBLIC. (My route is mostly along main roads.) Believe me, this is NOT like me at all. I am not what you'd call a natural athlete, and certainly not a natural runner. I look awkward, I'm in constant danger of tripping over, everything wobbles all over the place and I start puffing and turn tomato-red in a matter of seconds. Which might be okay, except that I happen to have a very round face - so I'm not just red; I look like I ACTUALLY have a tomato for a head.
Kind of like this, only with less smiling and more grimacing.
So you see, I don't exercise in public. That's part of the reason I bought a treadmill, so I could turn red and work on my cardiac arrest in the privacy of my own home. And yet, there I was this morning. Huffing, puffing, wobbling and turning red while cars drove by. No one stopped to render medical assistance, so it's possible I didn't look as bad as I thought. And when I got home I felt great. My body is getting stronger and my attitude to helping it get stronger is changing too. That's a win, in my book.
* By "bits of it" I mean I jogged in 30-60 second bursts, 4-5 times. At my current fitness level that's roughly equivalent to a half-marathon.
