In an endurance ride, discussed in this article, the winning horse is the first one to cross the finish line while stopping periodically to pass a veterinary check that deems the animal in good health and fit to continue. In the United States, most endurance rides are either 50 or 100 miles (160 km) long.dditional awards are usually given to the best-conditioned horses who finish in the top 10 for distances of 50 miles (80 km) or more. The Best Conditioned, or BC award is generally more prized than finishing first, as it is determined by a combination of speed, weight carried, and veterinary scores.
A penny is made up of 2.5% copper the rest is sodium and florite Nope, current pennies (from 1982 through 2010) are copper clad zinc. Starting in 2011 the mint is debating â¦several options from discontinuation to changing to use of a special steel alloy that is copper colored. Before 1982, pennies were bronze alloys of various types.

Nickels actually have much more copper in them -- 75% copper and 25% nickel. It's the same mix they have always had except for the World War II years, when silver and manganese replaced the nickel and some of the copper.
