The 404 Run

The 404 Run takes place in Atlanta, Georgia, on April 3, 2027. The event has one format, the 4.04 Run, a distance of roughly 4 miles (6.5 km), starting at 9:00 a.m. The name plays on Atlanta's 404 area code, and the slightly odd distance is the point rather than an accident of course measurement.

Four miles is a distance worth racing more often than most people do. It is short enough to run near threshold from start to finish, long enough that a reckless first mile will show up before the end, and it makes a clean spring fitness test between 5K season and longer summer targets. No special build is needed if you run regularly, though a few weeks of tempo work or mile repeats will help you hold pace through the third mile. Warm up before the 9:00 a.m. start and aim for even splits across the four.
