Marathon training tips?

getting from this point to a marathon is going to be a long journey. I would recommend you starting by setting your sights on a 5k. In order to run further, slow down. Even if it feels like just a tiny bit faster than walking. You should be able to carry on a conversation during easy runs. A lot of new runners make this mistake - they think running means sprinting. Sprinting comes much later. First you have to build your base.

Increase your weekly mileage by no more than 10%. Do not start doing speed work. No intervals, no hill repeats. Doing these without an aerobic base is asking for injury. Build to about 3 months of steady running before you start throwing in speed work (and only do one speed session in every 10 days or so for a while).

DO strength train though. Build up your glute, hamstring, quad, and core strength.

I run 5 times a week during marathon training, with 2 days of strength and one full rest day (one day is a short run/strength training; one long run; one speed/stamina workout; one recovery run, one mid-distance run). I start every morning off with 2 minutes of planks and a set of bodyweight lunges or squats. I run 50-60 miles most weeks. Obviously you are not going to be able to jump from where you are right into a plan like this. I would recommend being able to comfortably run 20-30 miles/week for a few months before embarking on an 18-week marathon training schedule.

As far as things like posture- here are some basics. Keep your arms relaxed. A lot of runners tense up their neck/shoulder muscles and carry their arms too high. Shake your arms out and drop them down at your side every so often to remind yourself to loosen up. Swing your arms naturally, but don't let them cross your body. They should be going forward (like you). Keep your posture upright (core strength!) this will keep your chest open and help in breathing. Your foot should land slightly in front of your center of mass. A lot of attention is paid to where your foot strikes first (forefoot, midfoot, heel), but where it strikes in relation to your body is more important.

Speaking of - get good shoes. Real running shoes. Fitted. From a running store. Drop some coin - save yourself from injury.

Good luck - and again, take this slowly, or you are likely to either injure yourself or have an entirely un-enjoyable marathon training experience.

Great answer you got there, so many new runners try to go fast to far to soon. Slow down and do walk run nothing wrong with that.
Start the Couch to 5 K program and move up to the 10K and then Marathon. You can do it but building a base is so important.
I have been off with a foot injury for months and hopefully have started to make my way back so I can run again and I will start right back at basics, walk run and build on that.

That is EXACTLY what I did! I did couch to 5k, then wanted more, so I did up to 10k. Then I wanted more. Now I am training for my first marathon and am running on average about 30-40 miles a week.

So umm... when is this marathon you are training for? I ask because most training plans are 12 weeks and 5-6 days of running, and that's just not enough time for a new runner. I would suggest tabling this goal and setting a more realistic one for you such as running a half marathon in 2014 and *maybe* consider a full marathon in 2015. You need lots of time and lots of miles before you're ready for a marathon, unless you like pain and misery.

Yes ma'am! Let me tell you fail/success story. I started out training for a marathon in October. I had never run more than 4 miles before and I hadn't run more than 3 miles in.... I can't tell you how long. My school has a program called Marathon High where they train the students to run marathons. I was inspired. We started training based on a book called "Marathon training for the non-runner".

Its 4 days a week. We did it Mon/Wed/Thurs/Sat. Saturday being the long run.

We made it to week 10 which was 16 mile long run and I got the flu. Then i got bronchitis. So after two missed weeks I started running again - an 18 mile long run - but felt like I just couldn't pick up where I left off. So, I am now training for a half marathon.

And for the record, I'm 27 and 160lbs at 5'2. So... .I am not in typical runner shape. So, if I can run 18 miles - I know you can do it
