RUNNING HELP

First up, what was the session you did? A mile plan might make you go a bit too fast, whereas a 5K plan like C25K encourages you to go nice and slow with walk breaks and is better designed to get you to your goal of 5K.

Three things cause pains when you start running - wrong shoes, running technique and just plain not being used to it. Please do NOT resort to your daps.

Did you get your running shoe properly fitted at a specialist running shop? If they're wrong for you they can cause problems, but to tell the truth despite everyone pushing running shoes on beginners, you should be OK in cross-trainers and the like until you start running half an hour or more.

Try not to over-stride when you run or to over-exaggerate the heel-toe action. Just let your foot fall naturally when you swing your leg forward - you might find you're naturally a mid-foot lander.

Finally as you're new to running, a few aches and pains are to be expected as you ask your body to do new things. Stretch, rest and ice any niggling aches.

I'm a veteran of running forums and the metallic taste has as many answers as people you ask! Here's one of the more sensible posts on the problem. In short, drink more water and run slower.

I'm sure I've pointed you at my beginner's tips before, but here they are again:

Remember point one - "When you start out, it’s HARD! Even if you think you’re fit, running is so different to anything else you’ve done before you will get out of breath quickly. Stick with it. Can’t manage a minute? Go slow. Still can’t? GO SLOWER! "

Good luck!

I actually try to use a half step. lean over like I'm nearly falling and try to use as little knee bending as possible.

The right shoes make all the difference!! I was getting shin splints and I went to a specialized shoe store where they properly fit you in the correct shoes for the way you run. I did not have an issue with shin splints until I started running for longer periods of time, but I could barely walk when they started. Since I've been fitted, I haven't had an issue...its been about a year ago...

1) Change your shoes (try a shoe store that has actual salespeople that KNOW shoes)
2) Breathing heavy can effect the taste in your mouth. The weather, the air quality, what you ate - all these things can cause a tatse in your mouth. Try a new piece of fresh gum befre you start running. When I used to run long distance I always had gum, your stomach can create some weird odors.

Thanks, ill give that a good friday - as for salepeople that know shoes - dont think there are any in my town!

Try Run and Become, Moti and Go Outdoors. I've been to a Run and Become before and they're pretty good - they let you run outdoors in the shoes you try. Bring your socks and current shoes!

If it is really cold outside I can taste the blood taste. It takes a few times out in the cold cold weather for everything to get adjusted where you don't have it anymore.

I agree with everyone that mentioned shoes. They make all the difference!

I was running with ill fitting adidas and had terrible shin splints. For Christmas I got asics gel kayanos and now I actually look forward to running.

I also started with the couch to 5K program. I'm on week 7 and LOVING it.

If you are just trying to run 5Ks, please do not drop $150 on Asic kayanos. They are amazing shoes. I have them, I love them, but don't spend that much, it's unnecessary.

The only thing I would add is be sure to do strength training. Do squats, lunges, leg curls, leg extensions, etc... build your muscles so they can withstand it.

Otherwise, great advise here.
