You will do great! Mind over body, except of course if you feel pain then body of mind lol. I "run" pretty slow just so that my body could get used to running. I just finished the C25K program and I was always trying to run fast, until I realized that I could accomplish a run if I slowed down. I am not working on speed because I'm comfortable running for a long period of time now.

Feel free to add me

You can do it! you must have just done week 5 day 3 with the 20 minute run - if you could do that then you can do this

What program are you using? Most of them have w5d3 as the 20 minute run and w6d1 as two 10 minute runs with a walk in between. Some of them, however do w6d1 as the 20 minute run and others don't have you put together a longer run until the end.

However, assuming that you have the most common version:

I can guarantee you that it will be the same amount hard as everything you've done so far. Running really only gets challenging up to a point. If if gets more challenging than that, you know what to do: slow down. This is not a race. There is no place you have to be.

You got out there and completed day 1 - for about 50% of people that was the hardest day.

You got through weeks 3 and 4, so you learned how to slow down and pace yourself.

You may have even completed a 20 minute run (that's where the other 50% experience their maximum challenge), so you have learned to push through those first 10 difficult minutes until keeping going becomes easier.

In the next few weeks, with the longer intervals, you will find your natural form and become more efficient. It's not going to get a lot easier, but you will start naturally getting a little faster and it will be no harder.
