It's been 3 weeks of 'Learn to Run 10K' training class and we're on to 2 1/2 minutes of walking + 2 1/2 minutes of walking x 9 (45 min). Okay, for anyone who has run before, you're probably thinking '2 1/2 minutes? That's easy!' - but when you haven't been much of a runner in your life, every increase in the amount of time you run is progress! We run 3 times a week and by the end (April) we should be able to run at least 3 x 15min intervals. On Tuesday I was on the treadmill and was feeling so good I pushed on to do a couple of longer intervals - 4 and 5 minutes of running. The knees are still achy but I'm finding that a little ice and a couple of Advil do the trick.
Anyway, my point is if I can learn to run, anyone can - the idea is to start out slow and keep increasing. It's motivating to increase the running and decrease the walking over time - it's measurable and you can see your progress.
Have a great week!
