Okay, I think I may try for a 5K (3.1 mi). Will have to find one coming up this fall.
In a nutshell, it says to start with 20-30 minute walks (sessions) 3 times per week with a day of rest in between sessions.
Put 3 1-minute jogs into your walk the first week (walk a few minutes, jog 1 minute, walk a few minutes, jog 1 minute, walk a few minutes, jog 1 minute, walk a few minutes).
Each week, increase the total time spent jogging at each session by 3 minutes. One minute jogs become two minute jogs the second week, then 3 minute jogs the third week.
Eventually (10 wks) you will be jogging the whole 30 minutes.
Stretch after each session.
I've done this a little on the treadmill over the past 8 weeks, but have not followed this formal plan and have done other cardio classes. Today I jogged 5 minutes, then 4 minutes in the middle of my 20 minute walk. The first time I walked in mid-July I was only able to do one 1-minute jog in my 30 minute walk.
So my plan is to continue my other cardio classes and use the treadmill more often, increasing jog time vs. walk time each week.
I've heard of other plans to 1) pick a distance (1 or 2 miles) and do it each time, slowly decreasing the total time to complete it, -or- 2) pick a set time (20 or 30 minutes) and increasing the total distance completed each time.
Anyone else want to try?
