The 400 freestyle is middle-distance swimming's signature test: roughly 5-10 minutes of sustained threshold effort where technique economy matters as much as engine. Unlike the 200, there's time to settle into a rhythm - and unlike the 800 or 1500, there's no cruising: the pace sits uncomfortably close to maximum the entire way. It rewards swimmers who can relax at speed, hold long efficient strokes, and negative-split with discipline.

Adult times, 25 m pool.
Find your rhythm in the first 100 and lock your stroke count per length - rising counts signal decaying technique before your watch does. Aim for even or negative splits; the classic error is a hot first 100 that costs 10+ seconds later. Use the walls: consistent streamlines off every turn add up to whole seconds over 16 lengths. Train with sets like 8x50 or 4x100 at goal pace with tight rest intervals.
Beginner: 4x100 m with generous rest at conversational effort, building to a continuous 400 with even pacing. Consistency across lengths is the whole goal at first.
