Long Run Progression: When I Add Miles (and When I Repeat)
How to progress long runs without ego spikes — when to add distance, when to repeat a week, and what “controlled” should feel like on Sunday.
Not every Sunday needs a personal longest
I chased weekly PRs in distance until my calves wrote a veto. The better skill is progression with cutbacks: move forward when the last long run felt controlled and the midweek days recovered, hold when they didn’t.
Repeating a distance with better fueling and calmer pace is still progress.
Small jumps, fewer heroics
Coaching practice and injury epidemiology both warn against sudden workload spikes. You don’t need a perfect percentage rule to respect the idea: big single-week leaps in long-run time-on-feet are a common way to get hurt.
I prefer modest increases and occasional down weeks that absorb fatigue. If midweek quality is already ragged, I protect Sunday quality before I chase a new peak.
Purpose over Instagram miles
Long runs teach patience, fueling, and time on feet. They are not weekly races. Keeping most of them truly easy is how you still have a nervous system left for Tuesday.
