A time trial is a set distance run flat out, against the clock. There's no pack to sit in and no finish-line sprint for position. Your time is your result, and the only person you're racing is you.
The trick is pacing. Go out too hard and the back half falls apart. Most people run their best time trial by starting a touch slower than feels right and finishing fast.
A short time trial, like a mile or 3km, is one of the simplest ways to measure your running fitness. Run it again a few weeks later and the clock tells you exactly how far you've come.

- 1,609 metres, or 1.61km. The classic distance for a flat-out run.
