题目内容
Come prepared: When you arrive at a race, your bike should be in race-ready condition.
Chain Management: Chain damage is still the number one problem with mountain bikes. Keeping your chain clean and well-oiled will help, as will frequent chain replacement. Periodic inspection of your chain for wear, stretch and damage may save you a long walk home.
Packing Tape: This can be used for rims trips, boots for fractured tires and a dozen more makeshift repairs. If you've flown to the race, it also saves you from having to borrow tape to close up your bike box for the flight home. Other musts: safety pins and plastic zip ties.
Pre-race: Visual inspections before any serious off-road ride, carefully examine the area where the tire hooks onto the rim and remove any foreign objects which could cause premature(比预期早的)tire wear.
Tire Pressure: Check tire pressure before race start. The recommended pressure is noted on the tire sidewall, usually 40 lbs., many racers run 50 lbs., or more for less rolling resistance.
Be Self-Contained: Make sure you are self-contained. Bring your own drinking water, food and first aid kit. Also have tools, spare parts, tubes, quick fills and a chain tool. Never suppose you can just borrow these items from a friend.
Post-race Visual Inspections: Inspect your bike after completing each event, especially before competing in a downhill event. Re-inspect before packing your bike for the trip home.

In February 2006, Lydia Angyiou and her two sons were walking through their village in northern Canada. The sound of children shouting made her turn around. To her horror, Lydia saw a 700-pound polar bear behind her eyeing her seven-year-old son. Getting between the bear and her child, Lydia yelled at the children to run away. She then began hitting and kicking the animal as hard as she could. A neighbor who heard all the noise came and shot the bear. But everyone agreed it was Lydia who had saved her children’s lives. A local policeman described it this way: “… I guess when your back is up against the wall, … we come up with super-human strength.”
Where does this “super-human strength”, courage and quick thinking come from? Experts say it comes from stress! In stressful situations, the body releases chemicals that prepare it to take action. These chemicals give people the speed and strength they need to fight danger or run away from it.
When we think of stress, we usually think of its negative effects. Studies, though, show that moderate levels of stress are actually helpful. In fact, the way we perform is usually affected by the amount of stress we feel.
Stress causes the brain to release adrenaline(肾上腺素) which in turn increases our energy and excitement. The chemical gives us clearer minds and helps us to do more. This is why some people say they work better under a deadline.
Adrenaline that is not released for long periods of time can cause us to increase and strengthen our abilities instead of weakening them. We sometimes turn out our very best work when we push ourselves to the limit. Stress can also make us more confident. Handling small amounts of stress now prepares us for handling serious situations in the future. Who knows? Today’s stress may even prepare for the next polar bear that comes along!
