The conversation I had with myself went something like this:
"You should skate to work today."
"Hmm, maybe, it'd be quite nice but I haven't timed it."
"Yes you have, you've skated that distance hundreds of times."
"But what about that ramp bit by the railway station?"
"There's a handrail, you can grab that if you want to stop."
"What if I fall over in front of people?"
"You've made a dick of yourself in public how many times and you're worried about that?" *slap*
"I don't want to get to work all sweaty."
"So wear a different shirt."
"I haven't skated for months, I'm really out of practice.."
"Like riding a bike, silly. Look, do you really want to sit on the bus on a beautiful day like this?"
"You're right. OK. Skating now.."
And you know what? It was fun. It took a bit of getting used to carrying weight on my back, and I was a bit wobbly to start off with, but I didn't fall over and it was really pleasant skating leisurely round the waterfront. It didn't really raise my heartrate any more than walking would, but it was faster and beats the hell out of walking to the bus stop for exercise. Also, with changes of shoes and clothes and the walk down the gorge, it only took 5 minutes longer than catching the bus would've, and it was free!
So yeah, go me. ;-)
