Where do you sign up for the childrens marathon?
My 11 year old son wants to run the 2011 childrens marathon ( 2 miles i think). Where can he sign up? Thank You!|||This of course depends on WHICH children's marathon. If you have a look on the events website that should have the details, or check the local press nearer the time
Is one month before a marathon too late to change running shoes?
Actually, I have had my current running shoes for 7 months only and they feel fine but I am training for a marathon so I dont know if I should just go ahead and change shoes now just in case. No current problems with the shoes I have now but of course I am worried that they may be worn out by the marathon which is still a month and a half away.|||Not really.
First of all, if you've trained in the same pair of running shoes, they may very well be worn out by the time you get to the Marathon. Thus, if you start using a new pair a month ahead of time, they will be properly broken in by the time Marathon Day arrives.
Remember that old shoes will not have the same foot protection as newer ones. When running 26.2 miles, you NEED that protection!
As a rule, running shoes are generally worn out by the time they reach 500 miles. It is not worth the risk to run a marathon in shoes that are 500 miles old.
By the way, which marathon are you planning to run?
Good luck, and good running!|||If they feel fine right now, I'd keep them, but if you'd feel better with new ones, that's ok too. It's always best to go by feeling.
If you've been tracking your miles, that's a great way to tell how much life your shoes have left. Generally I change mine around upper 300-425 miles, but that depends on the running and person. Most say they should last 250-450 miles. If you're close to the 350-400 range, go ahead and change them.
I'd recommend getting the same shoes again though, just the newest version because you're so far into your training and know they work for you. Now's probably not the best time to experiment with new ones, save that for after your marathon.
Shoes generally break in pretty quick, after one or 2 runs it seems like, so getting new shoes even a couple of weeks before probably won't hurt you. I'd keep running in these until the cushion wears down a little more.|||If you are running distance you should use more than one pair of shoes.
I own several pair and alternate shoes each day.
If you run in one pair until they are worn out, and then go to a new pair you may have problems with your legs and body.
Get another pair and use it along with the pair you are now using.
When one pair needs to be replaced then get another pair.
I don't know any distance runner who doesn't use several pairs of shoes for training.
One month is plenty of time to wear a new pair to be certain they are not going to hurt.
If you are racing in a different pair of shoes than what you train in you should wear them in a few 10Ks or training runs to be sure they will not hurt your feet.|||If you've been running in them that long, you'll need a new pair. Even though they might look fine, they could be broken down internally.
Be sure to break the new ones in with shorter distances and then gradually add greater mileage.
A month and a half is just about right. Have a great marathon!|||If I were you, I would pick up another pair and start breaking them in. As said before, many runners use two pairs and alternate them.
This is a good idea in case something happens to one pair (gets caught in a rainstorm, gets lost, attacked by your dog, etc.), you have another pair ready to go.
So get a new pair and start using them a couple times a week. When it comes to the actual marathon, just go with whichever pair is feeling best that day.
Good luck.|||If your shoes are fine, then don't change them. Although it is a good idea to rotate shoes, a month and a half is pretty soon.
If you decide to change them, get the exact same shoes and alternate between the new pair and the broken in pair...

How many cans of energy drink must be used for the marathon?
For a marathon, 24,000 liters of energy drink must be used. An energy drink contains 8 grams energy powder per 100 ml water. The energy drink contains a total of 1.25 kg. How many cans of energy drink must be used for the marathon?|||Strange question
Thats 2.4 . 10^7 grams of water + 1.92 . 10^6 grams of energy powder.
Total mass is 2.592 . 10^4 kg
Divide by 1.25 to get the number of drinks
Number of drinks = 20736

How many days before a marathon should I not do any activity?
Training for my seventh marathon. Race is on Saturday. I also swim on average 16,000 yards a week (4000 yards 4x a week). Very hard for me to "taper" without getting jittery. Is it okay to go three whole days w/o any formal cardio activity before the marathon? Serious responses only please.|||if the marathon was sat.

Can I run a half-marathon with only 15 weeks of significant training?
Hello,
I've been running for a few months now and am going to do my first 5k race in a week. I am comfortable running 3-4 miles and have been doing some tempo runs. I am considering training for a half-marathon that is in 15 weeks and am looking for some experienced runners feedback. I have a friend who I run with who has ran a half marathon and she believes I'm capable. I don't want to do anything to over-exert my body or train too quickly. Thanks!|||Yes but be careful. To avoid training injury do not increase your weekly mileage over 10%. To run the half marathon, you need to be able to run 4 to 5 miles daily at speed without wearing down.
On race day, cut back on your speed 30 to 45 seconds a mile. If you are like me, you will be able to run three times your daily training distance at that pace.
If it helps any, I went from running 10k races to running my first marathon with 4 weeks of running 42 miles a week at 10K speed. I don't recommend that anyone else do that but it is possible to get ready for a long race rather quickly.|||What is a few months?
If you are conditioned to your 3-4 mile days you could finish the half with 15 weeks of training.
You need to increase your distances a little.
The rule of thumb is you need to average 1/3 your race distance, that means you could finish the half, but not race it.
Be careful when running longer distance, I would suggest you do a long day of 6 miles or so, and see how you feel.
If you are not too sore then begin to incorporate a day or two each week, along with your usual 3-4 mile days.
After 3 to 4 weeks you can increase your average, along with one or two long days.
The half is "only" 13 miles so you don't need half the training as you would need for the marathon.
A common mistake for beginning runners is to increase their distances too fast, you will feel good, but unless you control your increases you can be injured, which will set you back.
Two weeks before the half do a 10 mile run on your long day, and then taper back to easy days, without any stress work.
The 2 days before the race, warm up, do an easy 10 to 15 minute run and then rest.
In the race go out at a comfortable pace, you will feel good, but don't get caught up in the excitement of the herd and run too fast.
Drink water at every station, even if you are not thirsty, stop and walk to drink don't try to drink while running.
You should do fine.
