Five-minute warmup then...
Alternate 60 seconds of jogging (6.2 MPH)
and 90 seconds of walking (4.0 MPH)
for 20 minutes
That ended up being about 1.6 miles, and I wasn't dead, amazing! I figured at that pace I might not be able to keep up and toward the end I'd shoot off the back of the treadmill...lol.
But I didn't!! It was a challenge...but a doable challenge and it felt GREAT!
After that I did some exercises with my stability ball.
After all that I felt like I got a pretty good workout.
The Run thru Purgatory is getting closer and I'm starting to get butterflies now...First Race....Scary!!
