At what weight did everyone start C25K?

I started around 230 lb - I repeated week one.

Right now I'm around 212 - tonight I finished a 2.5 mile jog in the rain!  The temp was perfect.  It was great!

I'm 5' 8.5"

I would say don't compare yourself - if you have issues with joints or other things there's nothing wrong with doing something else to build up strength.  While you won't "run" a 5k per say in the water, you can do water aerobics/water therapy and that will help significantly.  I did it this summer and I think it significantly helped me build up the c25k program.  

Good luck!

I started the program when I was 242. I was two weeks shy of completing the program when my 5k race came and I ran that when I was 217. I still run and just finished my first 10k and I weigh 183. It has gotten easier but I am sure that is a combo of less weight to travel with me and training. Listen to your body, it is wonderful and telling us what we need to or not to do.

I was 161. But you PT knows you and your physical limitations.

Also, I'm injured right now so I do all my long runs in the pool. Running through water is actually pretty hard work. It's not for sissies.

I started at 6'-3" and 345lbs.  I am on Day 3 Week 4 and I am still right at 330lbs.  I made it through the first two days of week 4 but it was not easy, not looking forward to week 5 at all. 

My goal is to enter a "Jingle Bell 5K" by the first week of December, I don't know if I will be able to run the whole thing or not but I am going to give it a try.

Thank you everyone for your replies. I am 41, I am at 235. My goal is at least 145. I am going to start in the water, I even have tennis shoes I wear in the water.

Again, thanks!
