A day a week off, with two off every 4th week. Always taking the day off if I feel exhausted, RHR is too high, or I feel like I'm getting sick. An example would be this week. I traveled 6 time zones away, and walked my buns off the preceding two weeks came back, and really only had the energy to run 3 days this week. Just made it a recovery week, even though i had a full week scheduled. If I take an unplanned day off, I don't
try to make up the missed run. For example, if I had a long run planned today, and a recovery run tomorrow, and I took
an off day today, I wouldn't then do my long run tomorrow, I just pick up the schedule as if I did the long run today, and do the planned recovery run tomorrow.
I hope this made sense!
