Running at over 200 pounds in weight?

I believe the CK25 app takes the WALK/RUN approach were you warm up for 5 minutes walking, run for a minute/walk for a minute. Gradually you start to run longer and the time walking is reduced.

considering that soldiers often have to PT while carrying/wearing 80+ pounds in gear/body armor/etc....and obviously the "average" military member would be > 120 lbs bodyweight...

there are very small/light people who can't run due to joint pain & there are people who are 200+ pounds bodyweight who it doesn't bother one bit.

give it a try; just start slow (low mileage) and see if it bothers you or not.

also worth making sure you're wearing shoes that are very supportive/properly fit.

just my $0.02

avg military wt is 175lbs. that is avg the ht at 5'10" I walked out of boot camp for the Marines at 175 and 6' ...put on 10 lbs right after and kept that healthy wt for the first 8 yrs in. then went to 195 for about the next 6-7...then crept up to 200-205 till the last 2-3 yrs..then it was about 210.... my gear was around 80 lbs (you are correct) but my pack was 100-120lbs..
ran 3-5 miles (up until the last few yrs) 4-5 days a week for about 45 weeks a yr depending on training, weather and deployments.

I started running every morning until last week. I ended up with peroneal tendonitis. I'm fighting to get my ankle healed. Just listen to your body and if I was you I would try to ease into it and make sure you add some strength training for your ankles and knees because if you haven't been do these type of exercises it make be hard on your joints. I'm planning to run a 5K but when my ankle heals I will definitely do things different. Make sure you have some really good running shoes and don't over do it. Blessings to you on your journey.

I'm 244 pounds (started running at 256), and I have been running a couple times a week since the beginning of the month. My joints aren't feeling any worse than they did before I started working out. In fact, they're feeling better! My ankles used to kill me after a day at work (I work on my feet all day on a hard, concrete floor). Once I had the chance to sit down after work, it hurt to stand back up. I'd walk with a waddle a little bit until my ankles warmed back up to walking.

Since I started running, that doesn't happen anymore.

If you want to start running, I say go for it! Just pay attention to how your body is feeling about it. If you find that you are experiencing any unusual pain in your joints, then lay off of it. But you'll never know until you try.

I haven't been doing the C25K program specifically, but I have been doing something similar. I've been introducing myself to running in intervals. At the beginning of the month I started out doing a 5 minute walk as a warmup, then I'd jog for 1 minute and walk for 2 minutes, alternating between the two for about a 15 minutes. Now, just a few weeks later, I do my 5 minute warm up and I jog for 3 minutes (at a faster pace, too) and walk for 2 minutes, and alternate between the two for a half an hour. I've even had a few days where I was feeling especially good and I just jogged for 10 minutes straight!

Running is so great, and I find it so much more engaging and effective than the forms of cardio I've done before. I used to stick to the stationary bikes or the elliptical machines because I figured at my weight that's all I could do. They both bored me so much, and I dreaded working out. I'm so glad I started running instead. Someday I hope to run a marathon.

Do your thing, girl! Find what works for you. If it's running, don't tell anyone tell you that you shouldn't do it, unless they're your doctor.

I started off by walking 2-4 miles every day back in January @ 310 lbs. Granite I tried to push myself to walk faster everyday. Early April I started a C25K Plan that Endomondo gave me where I was around 275 lbs. Since April I have been interval training (jog/walk) 4 days a week since April.

Over time I have become less sore and I feel that my joints are stronger. I am sure some of that is the additional weight I have lost throughout the time. I make sure I stretch well and I try to listen to my body. If I am overly sore I may wait until later in the evening to run or I may hold off until the next day.

I have a partial tore right Achilles tendon from drunken escapades over a year ago. The doctor had me go through PT to stretch and strengthen it because surgery is not needed for me and if I did my weight loss efforts would have been impacted. So even with a weaker right ankle I have been able to run from 275lbs to 250 lbs (where I am at today). I tell you when I run I feel even better and not as sore for not as long.

Get out there and take it slow. Walk the entire time if you have to. When walking gets too easy start jogging more and more. You need to determine if something is harmful to you.
