I would like to take an old soccer field in a run down park and make a flat track for my friends and me to race around. I would like the course to be 333 meters length so we can throw in some 1k races. Unfortunately I'm not skilled in math and don't have any real tools besides a long rope (200 feet) and my bike (with computer). I could probably come up with a tape measure if needed. So . . . what I would like somebody to do is explain to me how I could use these tools to accurately (or at least close) paint a line that we can race around.
The main way I thought I could draw the curve on each end of the track would be to use the long rope to paint two circles on the field, and then connect the two circles using straight lines. If I stake the rope in the ground, measure off a certain distance, then paint the circle as I travel around the center at the radius I selected, I should have a perfect circle. But, what radius (in feet) should my circles be, and what distance should the centers of the two cirlces be from each other? Or, if there is any easier way I would also be open for other suggestions.
Yes, this sounds dumb to some. But I think my friends and I will have a blast with this. The closest velodrome is a few hours away and I think this could be something cool to do in the off season. We all have track bikes and would love to put them to use. I would also imagine that we might even wear out all the grass and end up having a dirt track. This could be kind of cool as well. Tire selection could become very important and people would be encouraged to use their creativity.
Anyway, can anybody help with construction ideas? Any other ideas about things we could do to spice things up even more?
A short track mountain bike course could also be in the works around the perimeter of our fancy little grass track, which could add tons more fun.
Let me know your ideas.
