It's so funny how when i look at running distances in running event ads, i hear my brain saying: "5km, 10km... Easy peasy." But then when i remember the last 5km i did which was last sunday, my body said the complete opposite. And i realize that while i am mentally prepared to do distance (having challenged and conquered 21km), physically, i am not as fit as i would like.
You see. I've noticed that my right knee acts up when i walk/run for distances beyond 4km, and somehow, my breathing is more laboured than usual. And in general, both my knees are a lot more tender these days even when i am just simply moving around. And i worry that they are more tender than they should be for someone my age. I'm ONLY 24! I can't imagine the backlash i *might* get in future at age 50 or 60 or 70. Royal bummer.
I'm thinking of changing my main mode of sport. I've GOT to do something that doesn't tax my knees so, while at the same time, sustaining the kind of intensity that i love to have in my work outs. Shorter runs? Cycling? Brisk walking with short runs? Swimming? Pilates? Kickboxing? (NO AEROBICS FOR ME)
On a different note, i was very tempted to sign up for the Singapore Sprint Series Duathlon. The event consists of a 3km run + 15km bike + 3km run. Sounds ultra do-able! But the event is on the 4th of May, and that's way too soon. Ah well.
All righty. Time for bed, i've got work tomorrow!
