Successfully completed day 2 of C25K but I feel like my legs are going to fall off now

You are not the only one who feels that way! I never ran before -- the most I could run was probably 30 seconds and I would feel exhausted. The first week for me was really tough because it's a jolt. You go from barely running (or in my case, never running) to suddenly having to do 1 minute-2 minute intervals and I can tell you I felt like I wanted to pass out.

For me, the breathing and my heart rate were the toughest parts. I did feel like I wanted to collapse sometimes. My legs did hurt the first two weeks, but never too bad. So it could be normal soreness from your activity change. If at any time it feels like really bad pain like a sprain or shooting pain, it could be because you're starting this new routine or it could be your sneakers/the type of floor you're running on/etc. Also check your running form -- often the way you land on your foot can affect the impact on your legs.

I started the program in mid-February, stuck through it to the end, and just completed my first 5k on april 19th. Jogged the whole thing, and in a little under 40 minutes. Was I the best? Absolutely not. Out of 139 people, I was #116 to finish. BUT I DID IT. And you definitely can too. Your body will definitely adjust, but I can't say it ever really gets easy at all. That's because the program demands more from you each week so you're constantly pushing your limits. So many times I wanted to quit but I forced myself to do it and I feel better for it now that I actually finished. So keep up the good work! The mental is harder to battle than the physical - your body knows what it can handle and trust me it can probably handle more than you think.

Best of luck!

Totally , I was running 6k on the treadmill and found it very hard , started running outside and found it even harder , but each time it does get easier and you get stronger , the thing I learnt is that recovery and rest is part of the training ☺

I thought it was supposed to be done every other day, not every day.

When I started c25k, I was not even able to complete day 1. I was breathing, and panting so hard after just trying to run for 90 seconds that I thought I was going to die. But, I kept at it.

I go through four weeks, and took a couple months off because I started weight lifting. When I got back to it, I was barely able to run for two minutes straight. But, I kept at it...

From April 1st when I started again (although I'm doing my own thing loosely based off of c25k), I have increased my run time from six two minute intervals, to four seven-and-a-half minute intervals. So, I have gained 18 minutes total, and 5.5 minutes per run interval since the beginning of April.

The second day of each week was always the hardest for me. Day one, I'd think "Woo! Yeah! I got this!" then the second day, I think I'd push myself just a little harder and I'd think, "UGH! I can't!" Then day three, I'd be back to "Woo! Yeah!"

And yeah, it's supposed to be three days a week, or every other day.

Stick with it, make sure you aren't running too fast, and don't forget to stretch afterwards. It will get better, guaranteed.

I never really felt like that.. it was really hard and my legs felt like jello but I kept pushing. Definitely wearing good shoes helps and going at a steady pace. You should be able to talk to someone while running.

Hey Johnny! I am doing the program right now as well. I think I am on week 5. I have always been a runner off and on, but it has never been easy for me. Even with the C25K, every day is different. A lot of good suggestions here - get good shoes [this makes an unbelievable difference], stretch both before and after your workout, slow it down to a jog instead of a run, make sure you are getting the protein, carbs, and glucose to fuel your run [just don't eat within 2 hours of running], and drink plenty of water the day before your run.

My personal opinion:
I don't think you need to hydrate during your run because this can cause cramps. Just make sure you drink plenty of water on your off days and prior to running so you feel good. Unless your run is long or it is extremely hot, I wouldn't bring water. Sometimes chewing a piece of gum helps to keep me salivating so my mouth doesn't get dry. Maybe you could give that a try? Nothing super minty though!
Don't run two days in a row at first. You need to let your muscles recover. Try every other day or even every two days since you already have a great workout routine on your off-days. Protein powder with low-fat milk within 30 minutes of finishing your run can help your muscles recover faster.
If I am in the middle of the run and my legs start to cramp, I will sometimes drop down and do some push-ups to get some blood flowing to my arms instead. It distracts me from the leg pain and only takes a minute. Do this during your 'walk' portion so you don't miss out on the jogging.

Jogging outside is much different than on a treadmill and it is almost like starting all over again when you switch between the two. On my treadmill I usually do a slight incline [like 1.5] so moving outside is a little easier. At an incline you have to work a little harder to push yourself forward even with the belt moving. I think it mimics the concrete a bit more.

Good luck! If you want to be friends on the app let me know! We can help each other along!
