I knew it was just a matter of time, statistically speaking of course. On my morning commute today, I had my first stack. It happened something like this...

I was coming around a sweeping bend on a path when I misjudged the curve and my front tyre popped over the edge of the path onto the grass. There were trees on that side, so I tried to get it back on track, but unfortunately the path was about an inch or so higher than the grass, so the tyre couldn't get back up. A combination of my speed, my tyre scraping alongside the edge of the path and the slight downhill, off camber slope of the track saw me drop the bike and hit the grass on the opposite side of the path.

I consider myself lucky for a few reasons:
1. It happened out of view from most commuters, so the embarrassment level was relatively low
2. It happened away from traffic and other potentially dangerous situations
3. I landed on the relatively soft grass resulting in only a grass stain on my right shoulder and some minor bruising to my right upper ribs - must have fell on my trapped elbow or something.

Even though I was largely unhurt (and my bike totally unscathed), it still slowed me done a bit for the next km or so. Hope that's the last of them.

I'm not familiar with the term "stack", but it sounds like something that happened to me last summer. I had been volunteering late at night, and another volunteer offered to drive me home, which I took her up on. I took off my front wheel to load the bike in her car, which required unfastening the brake. When I unloaded it at my house and put the wheel back on, I forgot about the brake. My driveway goes up alongside my house, with a hill rising up to the house on one side, and downhill to the neighbor's driveway on the other. The space between the two driveways is shored up with rocks between 1 and 2 feet wide, dropping about 3 feet.

Well, I got on the bike and started toward the driveway before I realized I hadn't hooked up the brake. I realized it as I tried to slow down to turn into the driveway. I couldn't quite make the turn, tumbled down the rocks, and landed on the neighbors' driveway. I got away with a very small bit of road rash and a lost blinkie (lots of leaves over the rocks), but okay other than that. Luckily, it was late at night, and my ride had already driven off, so no one saw me!

As they say, you haven't completely learnt to ride untill you have your first fall
