What is the peak age of a marathon runner?
339004
Everyone's 'peak' age is different.  For someone like me, who ran their first marathon 3 years ago, I just ran a PR last month, so don't think I've peaked at marathons yet (I'm 40).\n\nHowever, here's some additional info on the age for the top ten marathon performances for US athletes from 2000-2005:\n\nMen: 30, 30, 28, 32, 30, 29, 30, 28, 27, 29. (29.3 avg)\nWomen: 30, 32, 29, 28, 33, 31, 39, 39, 35, 41. (33.7 avg)

There is a rule of thumb that says 220 minus your age, so 193.\n\nHowever, that is relative to your overall fitness and a number of other factors.\n\nIf you are trying to determine a maximum rate to use for training with a heart rate monitor, I have seen this method described in some of the literature.\n\nAfter warming up, run 800 meters "all out". That doesn't mean try to sprint 800 meters, it means run 800 at a pace that will give you your bets possible time.  Walk jog for the same amount of time as you ran. Run a second 800, at the same effort as the first. Immediately take/record your pulse. Use that value for all heart rate related calculations.\n\nIf you are counting your pulse, I would only go for 5-10 seconds because if you are at all in shape, your pulse rate will drop rapidly the first minute after you stop.  I would count for 6 seconds and then multiply the count by 10.\n\nRunnersWeb.com has a heartrate calculator here:\nhttp://www.runnersweb.com/running/hr_calculator_new.html

These are absolute minimums on the web site.  Max (where you want to be once you are a marine are 20 pullups, 100 crunches in two minutes and a 17 minute 3 mile run.  The other site is weight standards to enter and keep while you are in.\n**I just looked further.  There is no age difference anymore.  Everyone must comply with the standards of the 17-26 column

Middle age is usually when you have "peaked" and you have made it.  I havent got that far yet.  Looking forward to hitting middle age at around 55...because I plan to live until 110.

Everybody's a little different.  For example, a person's ability to run a marathon might be limited by muscular endurance (not having enough stored energy), or it might be limited by cardiovascular endurance (not being able to deliver enough oxygenated blood to the leg muscles).  In theory, you want these things to be matched pretty well--if you're pushing yourself to exhaustion.  For example, if your lungs crap out before your legs do, then you've basically wasted all that reserve energy you've got in your legs.\n\nWhat determines muscular performance?  Nutrition, muscle mass, regularity of exercise.  A lot can be attributed to the physical shapes of your bones and how the muscles are attached--that's stuff that you can thank or curse your parents for.\n\nWhat about cardiovascular performance?  Again, there is some genetic component to it, but this one is probably much more dependent on training--getting the heart rate up for sustained periods frequently.\n\nI'm willing to guess that most athletes are limited more by their muscular endurance, while most average people are limited by their cardiovascular endurance.

Just finishing a half ironman is a good time, but average age group triathletes usually consider a sub 6 hour time good while elite athletes often go below 4.5 hours

Why not? They have a 19 and under category for most races and even triathlons. I think teenagers are not in any danger from training for marathons. Small children (like 5yo) may develop problems as they are still developing at such a rate. They can run into enlarged heart and other physical problems but if they are under trained guidence I see no problem.\n\n I swam 2 very rigorous, 2 hour swim practices a day as a child and early teen and can only see benifit from it now.  My body developed very strong, large muscles and I think it helps me to stay in shape even now  being 30.  Im glad I did it.

a combination of both is best, short sprints within long runs as the long runs requires continous oxygyn intake and there for increases blood flow and all the good stuf that goes with it, namely heart rate, the sprints uses fast twitch muscles that onl use stored energy while the long twich (slower) muscles must use energy gained from the body and not stored.\n\nso i recomemmed starting out with a light/easy jog, for about 5 mins, building up to a flat run, maintain the flat run for as long a possible, then revert back to the easy jog, repeat the cycle\n\nthe body goes from light activity to heavy activity to an active recovery stage.\n\ndo no more than about 30 mins 3 days a week initally then when your body build up its endurance and strenght increase th eduration.\n\nif able to wear a heart rate monitor and aim to achieve a heart rate of (use the formula of) 220 - age *0.7.\n\nie age 31, so my max heart rate target would be 220-31 = 130 bpm\n\nososober

Depends on how much running you have already done in preparation.  If you are in reasonably good shape then you should be able to do some 10 or 12 mile runs. The problem with marathoners is they over train and run way too many marathons. That is not healthy. The body needs time to recover from the extreme strain put on the body in one marathon. I would vary the training. I would run 12 miles one day, then the next dsy fartlek five miles. Then take a day off.  The 12  miles is both warm up and good pace. The fartlek is a variety of paces over five miles. For example: Run a warm up then increase pace pretty good one mile, then jog very slowly with arms dangling, catching your breath, then hit it again for half a mile hard, then slowly jog dangling your arms, catching your breath. Then hit it again. Vary the distances and slowly toward the end run some sprints during the hit it phase. Get plenty of sleep and eat a well balanced diet. Drink plenty of water. Eat fruit and veggies for the electrolytes. Now if you are in poor shape then you are going to have to take baby steps. You have to run a 1/4 mile before you can run a 1/2 mile and you have to run a 1/2 mile before you can run a mile. You get the picture. IF you are not ready for the marathon, then pass it until you are ready. No one holding a gun to your head to run it. Be sensible.

Runners World often has good training plans. I also really like Marathon Guide. If the 1/2 is still several months off would be the ideal situation. You need to be putting in one to two long runs a week until you build up to about 14 miles. Running 5-6 days a week is ideal. You should do one day a week of speed work to help your overall time. Sorry to be vague but without specifics like how far away, how much you are training, it is hard to advise.

35 years of age to run, and you have to be a native-born U.S. Citizen.  This means you have to be born EITHER 1) In the United States or 2) to U.S. citizen parents (anywhere)

Ultramarathoners can exceed 50 miles without stopping.  Cavin Woodward's 50-mile best of 4:58:53 is under 5:59 per mile pace, and Don Ritchie's 100-mile world mark of 11:30:51 (under 5:59 per mile pace) Jose Cortez set the American road record for 100 miles at age 19 with a 12:54:31. \n\nThe way your question is phrased is the problem. Running a marathon doesn't necessarily make one a marathon runner. A novice may run for 25 minutes and need to stop and walk for 5. An experienced  "Marathoner " may not need to rest until the race is finished.

its very good... Becareful tho.. Marathons put alot of wear and tear on a body/ joint that may still be developing

If you have access to academic databases through a university, there should be lots of info in medical journals.  I'd also recommend referring to your local running club and contacting their leadership; if they can't find the exact info you want, they'll know someone who can.

There's too many x-factors with a question like this to offer effective advice.  No idea how fast you are now, how healthy your present lifestyle is, what monetary resources you have to sink into this goal, etc etc.\n\nThat's especially true because 2:50 over 800 meters is a pretty fast time for a non-elite runner.
