So I'm doing it!
Last Thursday, I started the C25K program. Since I'm new to running, I'm taking it a little slower. So instead of running for three sessions then moving to the next week, I am going to do Week 1 through the end of this week. That way, I can build up my endurance and muscles so when the intensity increases, I'll be ready!
I'm following a mix of podcasts/apps. On Thursday, I used the C25K app and that version of the program. It had me alternating 30 seconds of running with 90 seconds of walking for 20 minutes, with 5 minute warm-up and cool-down walks. On Saturday and Monday, I followed the 5K101 podcast, which had me alternating running for 2 minutes with walking for 3 minutes, for 20 minutes with 5 minute warm-ups and cool-downs. Tomorrow, I'll go back to the C25K version, and I haven't decided what I'll do on Friday yet. I like this approach because it varies things up a bit to keep things interesting.
I've read a good deal of information about proper running form and how to take care of myself before, during and after a run, so I'm not going in blind. One of the biggest things I keep in mind is that this isn't a race - speed and distance at this point isn't important. The most important thing at this point in my development is building endurance. So while I may run for 2 minutes, I might not get that far. But I run for the entire 2 minutes. If I start to feel sore or breathless, I slow down, but I keep running. And so far, this has worked really well for me.
Of course, I've run about 24 minutes total so what do I know?
By the way - since I started walking (and now running) with my Fitbit and tracking my food with the program (about 2 1/2 weeks), I've lost 4.5 lbs. That's pretty motivating, too.
