Running 3 miles a day bad for you?

Is running 3 miles everyday bad for me? I also like to mix in some bodyweight/circuit training ie. Jillian M dvds as well as running.
I'm not really running as in sprinting but alternating jogging/walking.

Running is cardio, and is burning calories and building stamina, and is therefore healthy.

Unless you're causing injury, RUN, BABY, RUN!

Thanks for asking....I was wondering the same thing

nope - not bad at all

3 miles isn't really enough to necessitate days off. It may seem like a lot for a beginner, but once you are used to distance running, 3 miles is a short jog, if that is all you do that day it is more of an active recovery day than anything.

That's only 21 miles a week if you never take a day off. Right on the fringe of where you might get overuse injuries over time. You should be able to sustain less than 20 miles a week for decades.

Though over time you might want to get in to a more varied running training approach. Some longer, slower runs, some shorter, faster runs and/or intervals in addition to workouts where you push yourself hard on a race distance (5K in this instance). It keeps it interesting and helps you run faster and more efficiently at the race distance.

in my opinion if you are trying to get "lean" or "toned" running 3 miles a day is not necessary.. the body will adjust rather quickly to the cardiovascular exercise and you will burn less and less calories each time which at that point you have to increase the speed of your 3 mile run or up the mileage... also as one guy said you have to eat daily necessary protein and fat requirements so that the body does not use muscle tissue instead of fat.. running is rough on joints if you do it every day (i have done this before) its more efficient to stick to a solid diet and a weight lifting regimen rather than doing moderate pace cardio. however if you are training for a race, you do what you gotta do. im just talking from a lowering body fat % perspective.

again, just my opinion

If you are otherwise healthy I can't think of any reason it would be bad for you. I ran 3 miles every day weather permitted (ran all year, but not in heavy rain or snow, lightning, or if the temp dipped below 20 F) for years when I was in my 30's and it was very good for me. Kept me healthy and looking great.

It depends! Did you jump right into running 3 miles every day or did you slowly work your way there over a long period of time? I ask because last year I went from running about every other day to ever single day all of a sudden and after a couple of weeks of that, my hip got completely messed up and i couldn't even walk for a week, couldn't run at all for about 6 weeks! Ouch! Doc said it is best not to increase total weekly mileage by more that 10% per week. So say you are currently running 10 miles a week, the next week do 11, the week after that do 12.1, the week after that do 13.2, etc. And take a day off sometimes! Recovery days are a wonderful thing.

My GF has been running 3 miles a day for almost 365 days a year - nonstop. I really was nervous about this but she is on day 327 and has not missed a day because of anything - sickness, snow, crazy storms... So it can be done.
