Running Mileage Planner
Plan and record weekly running mileage with pace per run, route, and terrain (flat, hilly, trail). Built-in fields for easy/tempo/long-run labeling so you can sanity-check your weekly mix isn't all junk miles.
Most runners can tell you their total weekly mileage without thinking twice, but ask how that mileage was actually distributed across easy runs, tempo work, and long runs, and the answer gets fuzzy fast. That distribution matters more than the total number alone — two runners logging 30 miles a week can be training completely differently depending on the mix, and only one of those mixes is likely to be sustainable without injury.
Why the mix matters more than the total
A widely cited guideline among coaches is that roughly 80% of weekly running volume should happen at an easy, conversational pace, with the remaining 20% reserved for harder efforts like tempo runs or intervals. Most recreational runners, left untracked, drift toward the opposite ratio — running most runs at a moderate-hard effort that's too fast to build real aerobic base and too slow to build real speed. A mileage log that separates run type, not just distance, is what makes this ratio visible instead of assumed.
The long run deserves its own line
Track your long run separately from the rest of the week's mileage, including its specific pace and how it felt in the final third. The long run is usually the single most important session for endurance gains, and it's also the one most likely to be either skipped under time pressure or run too fast because it's the one session people are most likely to push on for a sense of accomplishment.
What several weeks of logging usually reveals
Runners who log consistently for a month or more often discover their weekly mileage is far less consistent than they assumed — a strong week followed by a quiet week followed by a sudden jump, rather than the steady progression they pictured. This pattern, sometimes called the "weekend warrior" trap, is one of the more common precursors to overuse injuries, since the body adapts to consistent moderate stress far better than to sporadic spikes.
It's worth noting terrain alongside distance and pace. A hilly 5-mile run and a flat 5-mile run produce very different training stress despite an identical mileage entry, and conflating the two in a log can make pace comparisons across weeks misleading.
A common mistake: chasing weekly mileage records
Increasing weekly mileage by more than about 10% from one week to the next is a commonly cited threshold for raising injury risk, yet it's an easy trap to fall into once a log makes the previous week's number visible and inviting to beat. The log is most useful as a tool for noticing this kind of jump before it happens, not as a scoreboard pushing you to top last week no matter what.
Frequently asked questions
How much of my weekly running should be easy versus hard effort?
A commonly cited guideline is around 80% easy, conversational-pace running and 20% harder efforts like tempo runs or intervals. Most runners, left untracked, end up doing the opposite without realizing it.
Should I log my pace for every run?
Yes, pace alongside distance gives a much clearer picture than distance alone, especially for spotting whether you're recovering well between hard sessions or quietly running every run at the same moderate effort.
How much should I increase my weekly mileage by?
A commonly cited guideline is no more than about 10% per week, though individual injury history and experience level matter too. A log makes this percentage easy to calculate and check before committing to a bigger week.
Why does terrain matter if I'm just tracking distance?
A hilly run and a flat run of the same distance create very different training stress and pace outcomes. Noting terrain helps explain pace differences that would otherwise look like inconsistent fitness.
What's the most important single run to log accurately?
Most coaches would point to the long run, since it tends to be the most important session for building aerobic endurance and the one most at risk of being run too fast under the pull of feeling good early on.
Is this tracker useful for beginner runners too?
Yes — for beginners it's especially useful for preventing the common mistake of increasing mileage too quickly, which is one of the most frequent causes of early running injuries.
