Hi,
Use the app as a guide and personalize to your own schedule and health. My work schedule dictates a bit along with travel, etc..... I do not run more than every other day and due to my schedule skip on Fridays to run on Saturdays. As you mention.....the longer runs in there become a 'time' issue for me.
My week consistently is: M, Wed, Sat - Run with the app. T, Thur, Fri, = cross train....a walk, yoga, weight training, swimming, etc... and then one full day of rest...usually Sunday, but, I do some yoga that day as well.
Personalize the app to your schedule, but, you can't go wrong with recovery days. On a day where a long run was dictated....I couldn't finish and had a "do-over" ....so many elements go into a good run and a bad run, LOL.....I've been doing this for awhile now and I'm finding food, hydration, etc... are all become significant to the process.
Good luck and know it's your timetable and schedule!
