What's the farthest you've ever been on your own steam?

The farthest I've ever been on my own steam was quite recently. I've been doing a LOT  of skateboarding lately, and I've also been wiping out quite a bit too. Well, I got into using the board twoo days ago and I was practicing all day long and all night long too. I did not sleep. On that day I wound up bruising the bone in my wrist, slicing my palm open on a rock, and scraping my elbow. I didn't stop though. Then yesterday I kept going. I wound up taking a couple of rougher falls. I bruised the bone in my thumb, my knee, and my thigh. I also opened up my hand all over again, making the cut wider, and did the same with my elbow. Right now I can still barely walk or hold my books. I did sleep last night, but I think my total sleep time was about two hours. I'm still going though, and I have no intentions of stopping unless my girlfriend yells at me. Since that hasn't happened yet, I'm gonna keep going. So, all together I've been going about two days with a few injuries. I'm pretty impressed that I can still make myself go.
