there is different types of racing there is bmx, road, x country, down hill and cycle cross. so find out what you want to race the search the wed for comity's and tracks (for bmx) there are a lot of down hill races at wistler find a schedule.
All of them...up hill is so hard!
they do that so it does not roll down hill
In the old days, lumberjacks needed a fast way to get off the hill and back home, so they had races laying down on sleds down the hill.

so your car doesnt roll down the hill
gravity is the one to blame . gravity pulls down the biker closer to earth so it goes faster going down and slower going down
So they can have momentum for the rest of the ride. If there was no big hill, then you would constantly have to be pulled by the chains, and that's no fun. But if there is a big hill at the start of the ride, then you go down, down, down, and have enough of that speed/momentum that will keep you gliding along.
quite popular because it is so fun
I find mountain biking exciting and fun. It is also technical, so it requires some thought, like when getting over a jump. Also there is some great scenery, like when I was biking in France, Holland and Scotland I found it funner than road biking too.
The car driving down a hill will have the greatest kinetic energy due to its larger mass and likely higher velocity compared to the 1 lb ball rolling and the 200 lb person running down the hill. Kinetic energy is calculated as 0.5 * mass * velocity^2, so a higher mass and velocity will result in greater kinetic energy.
Rolling down a hill involves both potential and kinetic energy. At the top of the hill, the object has potential energy due to its height. As it rolls down, this potential energy is converted into kinetic energy as the object gains speed.
