"...The Stages of Twilight
For clarity, the definitions below will be for evening twilight, after sunset. The same subcategories apply during sunrise as well, but in the reverse order.
Solar twilight begins when the center of the Sun has passed below the horizon. The Sun as viewed from Earth is about 30 arc-minutes, or half of a degree, in diameter. (One degree is approximately the width of a pinky finger when viewed at arms' length.) Once the center of the Sun has set, the upper 15 minutes of the Sun will still be visible for a brief period. This lasts longer when viewed over the ocean, as due to the curvature of the Earth, the Sun is setting below the astronomical horizon - an imaginary plane perpendicular to a line pointing directly above the observer.
When the Sun reaches six degrees below the horizon, the period known as civil twilight begins. Although the Sun is no longer directly illuminating the ground, it is continuing to illuminate the upper atmosphere. During civil twilight, there is still enough illumination in the sky for most outdoor activities without the need for artificial lighting. Bright celestial objects such as Venus and Sirius will become visible. Also visible during this period is the shadow cast by the Earth on the atmosphere, which appears in the sky opposite the setting sun as a purple or dark blue band near the horizon.
Civil twilight is used in many local jurisdictions as the official legal beginning of night for national and local laws on headlight use, aviation safety, streetlight lighting, noise restrictions, and where criminal laws specify stiffer penalties for crimes committed at night.
The period after civil twilight, when the Sun is between six and twelve degrees below the horizon, is known as nautical twilight. During this stage of twilight, the sky has darkened considerably and outdoor activities are no longer possible without artificial lighting. The name "nautical" refers to the fact that at this time, navigation at sea via the horizon is impossible.
Nautical twilight is also critical in the planning of nighttime military operations. The Army Field Manual lists the acronyms BMNT (Begin Morning Nautical Twilight) and EENT (End Evening Nautical Twilight) as key pieces of data to be collected when gathering intelligence about a location.
The final stage of twilight, when the Sun is between twelve and eighteen degrees below the horizon, is known as astronomical twilight. Though skies are generally dark enough during this time to see planets, stars and other bright sources of light, dimmer objects such as nebulae and galaxies are not yet visible. The ideal period for astronomical observation of these objects occurs only when the Sun is greater than eighteen degrees beyond the horizon after sunset or before sunrise.
Visibility of celestial objects during astronomical twilight is also dependent on other factors such as light pollution, humidity, and the phase of the moon. In remote, arid areas during a new moon phase, stars up to 6th magnitude - the dimmest stars that can be seen by the naked eye - are visible during astronomical twilight.
The Duration of Twilight
Twilight can last from several minutes to several hours, depending on the latitude of the observer. In the polar regions, twilight conditions can persist for a couple of weeks before and after the perpetual night of the winter solstice. Near the equator, on the other hand, twilight can pass in about twenty minutes. Web sites such as Weather Underground or the NOAA Solar Calculator can provide twilight times for any location on Earth. ..."

Planning a Menu
What's for dinner?
As an outbound backpacker, your answer to that important question was made days, maybe weeks in advance. When you finally make camp after a full day of vigorous exercise, you're going to want to be happy with the decision you made. You want food that will nourish you, strengthen you, revitalize you and taste really good.
How Much Food Is Enough?
The National Outdoor Leadership School estimates that backcountry travelers burn between 2,500 and 4,500 calories per day, depending on their individual physiology and their activity. That translates into roughly 1.5 to 2.5 lbs. of food per day.
In a diet-conscious society, that may sound like a huge caloric intake. But food is the fuel your body burns as it powers up and down wilderness terrain. Finicky eaters typically morph into indiscriminate chow hounds after a few high-output days on the trail.
Anticipate that you will feel hungry often and that much of your quiet time on the trail will be spent thinking about food. It's true! Plan ahead for this stomach-gnawing reality.
If you're facing a borderline decision about how much or little to carry, take a little more. Feelings of unsatisfied hunger can distract you from the other sensory joys of a great hike. One of the 10 Essentials for an overnight trip, in fact, is a supply of extra food. One day's worth of food is a smart emergency backup.
On the other hand, don't overdo it. A common beginner's blunder is to bring too much food on a trip, forcing you to lug unwanted bulk and weight in your pack. Experience will teach you what amount of food works for you. Consider a few basic guidelines:
Factors to Consider
•Taste—Eat what you like. Don't try and convert your taste buds to new types of food deep in the backcountry.
•Calories—Don't inaugurate a diet program during a multi-night hike. You'll need ample calories (and water!) to fight off fatigue and headaches.
•Nutrition—It's fine to tear into a candy bar during a trip, but for the long haul you want to rely on complex carbohydrates and proteins. Intelligent quick-eats such as nuts and dry fruits provide a stable flow of energy to your muscles.
•Weight and Bulk—Stick to lightweight and low-bulk foods as much as possible, especially on long journeys.
cross country in 3 weeks?
1 of all make sure u have proper clothes running shorts t-shirt runing shoes ect.
2 u got to be motivated pick the reason ur doing this lose weigh with states something and focus on it
to help yourself stay motivated while u run write words on ur hands like champion of ur bf and when u feel tired u can look down and it'll help u push on
its much easier to run with a group too so maybe try and find a couple of friends to run with you or possibly a camp www.deckerrunningacademy.com (if u live near me)
3 don't run in the heat of day either wake up early before the sun (is a lot better) or after it goes down it'll be much easier
4 stay hydrated a god runner drinks an average of a gallon of water a day (gatorade is good too but not all u still have to have some water
5 PAIN IS BAD fatigue aching and sorness is good but burning or pain is bad if u feel pain stop and take a break
6 remember to stretch before(dynamic) and after (static) every run the more limber you are the better a runner you can become
7 pace yourself if you don't casually run then don't start off running 5 miles a day start with maybe 1-2 and SLOWLY progress upwards when u run ur actually tearing down your muscles and then when you r resting they a rebuilt stronger so take a day 2 off a week for sureif your running in a hilly area don't feel like you have to run the whole time walk if you need to and as you progress do more
8 safety to help keep yourself fit to run here are a few pointers staying hydrated means drinking a lot the night be fore not 5 minutes before u run it will just sit in your stomach and do u no good downhills do nothing but bad for u walk the downhills running down them is bad for your knees if something is bothering you after a run strech it out and then that night ice it if you get cramp while ur running stop push on the spot hard and breathe out ALL the air in ur lungs should get rid of them
thats all i can remember right now hope it helps took a long time to help if u got any questions email me and remember
"To give anything less than your best is to sacrifice a gift."
"It's a simple choice: We can all be good boys and wear our letter sweaters around and get our little degrees and find some nice girl to settle, you know, down, with...take up what a friend of ours calls the hearty challenges of lawn care..........Or we can blaze! Become legends in our own time, strike fear in the heart of mediocre talent everywhere! We can scald dogs, put records out of reach! Make the stands gasp as we blow into an unearthly kick from 300 yards out! We can become God's own messanger delivering the dreaded scrolls! We can race dark Satan himself till he wheezes fiery cinders down the back straightaway! They'll speak our names in hushed tones,"those guys are animals" they'll say! We can lay it on the line, bust a gut, show them a pair of clean heels. We can sprint the turn on a spring breeze and feel the winter leave our feet. We can, by God let our demons loose and just wail on."
"Games require skill. Running requires endurance, character, pride, physical strength, and mental toughness. Running is a test, not a game. A test of faith, belief, will, and trust in ones self. So hardcore that it needs a catogory all to itself to define the pain. When game players criticize, it's because they aren't willing to understand, not because they're stronger. Running is more than just a sport; it's a lifestyle. If you have to ask us why we run, you'll never understand so just accept."
