I'm looking for a 3 workouts/week training plan for a marathon. There is one on Garmin connect but it has a lot of walk breaks within all the long runs. Why is that?
For example, even two-three weeks before the race it suggests workouts like this: Walk in Z2, brisk pace, 5 minutes. Run in Z3, marathon pace 25 minutes. Repeat 4 times.
So it actually suggests 20 minutes of walking in brisk pace. Is this really recommended?
Is there any other place where I can find training plans which can be imported in Garmin connect and eventually into my Forerunner 735XT?
