Other Military Test Distances
This page rounds up every fitness-test question on the site that isn't the standard 1.5 mile (2.4km) run — covering the Army's 4km test, the 800m-and-5km police combination, the 2.6km referee test, several mile-based Air Force and army standards, and reader questions built around tight timeframes or training through an injury. Use the links below to find the page that matches your actual test distance and situation.
The 1.5 mile (2.4km) timed run is the most common fitness test you'll come across for police, military, and emergency service roles, and it's the focus of most of the running advice on this site - including the main 1.5 mile test training guide. But it's far from the only distance in use. Depending on the force, branch, or sport you're testing for, you might be asked to run a single fast mile, a 4km time trial, a combined 800m-and-5km session, or something else again. This page brings together the reader questions and advice that don't fit neatly under the 1.5 mile banner, so you can find guidance that actually matches the test in front of you.
The Q&A below covers a genuine spread of scenarios. There's the Army's 4km run against a 20-minute cutoff, the 800m and 5km components used in some police fitness tests, and the 2.6km test sports referees and officials are required to pass. There are also several shorter, mile-based tests - the 1 mile Air Force standard, the 2 mile test some army units use, and a couple of readers preparing for police academy entry on tight timeframes. Some of these readers have a year to prepare; others are weeks out and dealing with an injury on top of everything else. I've tried to keep each answer specific to the distance, timeframe, and circumstances the reader actually described, rather than giving generic advice that doesn't account for what their test demands.
If you haven't already, it's worth reading the main 1.5 mile guide first, even if that's not your test distance. The core training principles there - building an aerobic base before adding intensity, structuring interval sessions properly, and pacing the test itself rather than starting too fast - apply just as well to a 4km or 2 mile test as they do to 2.4km. What shifts is the emphasis: shorter tests lean more on speed and pace judgement, longer ones like the 5km or 4km lean more on aerobic endurance. The individual Q&A pages below go into the specifics for each distance once you've got that foundation.
A few of the related pages further down cover ground that's useful regardless of which distance you're training for - beginner-friendly programming, treadmill pacing if you don't have access to a track or accurate outdoor distance, and general advice on building mileage without breaking down. Worth a look even if your specific test isn't listed above.
