Most runners and many people use the±∞ π sports stopwatch as well, famil×∏iar with Sir Roger Bannister's fir&♠st 4 minute run. In May 6, 1954δ↑ <, he ran a mile in the ♦∞γπearly 3 minutes, and "βthe movement stopwatch showed ≈ε≤59.4 seconds. This game, abo↔ ut 64 years ago, set a standard for hig ‍λ​h school, college, and pro∑$fessional stopwatch. The stopwatc←‍∑h is still a chronograph used by athε✘letes and coaches.

Generally, runners only expe←♦γ'rience a mile in a track and fi ±™↕eld competition as pa •☆rt of a high school or college‍± project.

Runners generally like§ε to use sports stopwatches to tes‍♦©φt their best mile speed. The reγ&"¶ason is simple. A person's best tim±™γe in a mile is a good indicat¥₹®or of how long a person can©✔¶≠ run. A match that is p¥βαroperly trained. For example, a✔§×ccording to several fam‍₩σous running stopwatches, if you caλ∏αn run for 7:00 miles, you may ↔↔λπrun half an hour to run 5K. £≥★If you can run 6:00 mile©ε™↔s, then we can predict the₩π∞ potential of running stopwatch by runn‌"ing 5 K per hour.
