I never heelwalked. I could never run worth a damn, because I listened to the PT instructors at my school in the mistaken belief that they knew WTF they were talking about when they told me to run heel-and-toe. So I'd pound down the track jarring myself from head to foot, and come in five seconds behind the next slowest runner at 100 yards.
Then when I was about 26, I discovered that what worked for me was to run on my toes. And suddenly I could run like the wind. I left everyone else I knew as though they were standing still. And it didn't feel awkward and ponderous, it felt GOOD. I could feel the wind of my own passage. It felt almost like flying.
I learned to run almost silently, if I wasn't running all-out. When I was in hospital once after a breakdown (medical malpractive, overdose, general Very Bad Scene) I didn't sleep for about three days. I just couldn't sleep, I was too ... wired, for lack of a better word. So I'd wait until everyone else was asleep, and then get out of bed and go silently running laps around the quad.
In theory, running wasn't allowed in the building. But I just gave the night intern a quiet wave as I went past the desk the first time, and he looked at me and I guess decided I was OK, and just left me to it.
The third night, one of the other patients tried to join in. But he was heavy-footed, and couldn't shut up and just be, he had to try to hold a conversation. The second lap after he joined, the night intern told us we couldn't disturb the other patients and would have to go back to our rooms.
There wasn't a fourth night, because after three nights unable to sleep, the sleep dep was really starting to get to me, and they gave me some sleeping meds.
