Not real sure what information you are requesting. Here is the most comprehensive site I have found.

Marathons originated with the battle of Marathon.  After the Greek victory, Pheidepides(?) ran 26.3 miles to tell of the victory.  He screamed: "Nike!Nike!" and then died from exhaustion.  *Nike is victory in greek.

You can get the answer if you look up sites like  http://www.lonepinechamber.org/events/ \n\nThe Palms to Pines race starts in Death Valley and goes to Mt. Whitney covering 130 miles, including 15,000 ft elevation, Now thats a marathon!  I've only walked the trail as I perfer to see the beauty and not a blur...and running or walking is VERY strainiuous and at around 12, 000 ft I got tunnel vision and head aches. I never saw anyone using oxygen. Good luck but go prepared!

Any Marathon under 4 hours is competitive for an Amateur.  But many people are happy with +5 hour times.    Train to a pace, that is the key. Don't push yourself too hard.  Your first goal should be to finish.  There will always be another race waiting for you.

www.boston.com or www.marathonguide.com\n\nboston athletic association's website should have frequent updates too.  enjoy!

The average marathon is about 3.5-4 hours. Marathon runners have to pace themselves so they don't die, and still some do die. The record time set for marathon wasn't done by a man who sprinted.\n\nHe would be hard pressed to sprint top-speed for 40 minutes even if he was a super athlete.

I have done 2 marathons and many other races. Detroit has pretty cool marathon medals but there are many out there. They are all cool. I ran a half in nashvile and it was in the shape of a note. I ran a half in HELL michigan and it was a skull..... lots of medals out there but I guess it really isnt the medal that is important its the accomplishment that you did to get the medal.

I wish. The longest run I've ever gone on was about 5 miles. I've probably hiked around 30 miles in a day a couple times. Not too exciting. I want to be able to run a marathon in the next three years.

Track dimensions are going to vary. Most run about 110 yds on the straightaways and 110 yds on each of the turns which give you a radius of 35 yd.\n\nAccording to one rules document that I found, a standard 400m track is going to have curves with radius of 36.5 meters.\nThat gives you total distance on the curves of 229 m. That would make the straightaways 85.5 meters long.\n\n400m = 437.44 yds

Check with USATF. \nThey may be able to put you in touch with a local program. \nYou could also check with the local running shoe stores. \nFind out what running clubs there are in your area. They may sponsor something or know who does.
