But it’s so fun to get back in shape. The progress is so tangible, and week by week you can feel the improvement. Celebrate the longest run of X months, the fastest mile, the healthiest day, etc. Some days will inevitably be better or worse than others, and you have to do all the little things with even more of an emphasis. Enjoy that a slow run is still a run, and a step, no matter how small, is still moving you towards the eventual goal.
