You're going to need rest days. You're going to need them for your physical and mental health, so be sure to schedule them systematically in your weekly plans.
You do not want to risk injury or getting burned out (just as debilitating) by doing too much each week. I usually do one rest day and one easy day. Easy meaning I don't time myself, or the distance, and take walk breaks liberally. 45 minutes to an hour of soft, easy exercise. It helps keep the head clear and I usually find myself getting great ideas on these days. Exercise fuels creativity.
Fight that nagging voice that tells you you're being lazy on rest days. You need them.
Some ideas for what you can do during rest days to help you feeling good about your plan.
- Get out your yoga mat and do some light stretches and relaxation stuff.
- Write a weekly recap of your training. It'll remind you just how good you're actually doing.
- Do an outdoor date or family night out.
Do good, do life
