The start line is the part everyone sees, and it is the last fifteen minutes of a morning that began four hours earlier. Races almost never fail at the gun. They fail because something upstream ran late and nobody noticed until it could not be fixed.
This is the timeline we actually run. Times are relative to the gun, so T-240 is four hours before the start. Adjust the numbers to your event, but keep the order: the sequence is what matters, and it is the part most schedules get wrong.
The short versionThe first three hours are a build. The last hour is verification and crowd control, and it contains two hard gates: the course ride-through at T-60 and the final go from your course team at T-10. If either one slips, you are not starting on time, and knowing that at T-10 is much better than discovering it at T-0.
The build: T-240 to T-90
T-240. Director on site.
T-210. Portable toilets and staging delivered, setup begins.
T-195. Equipment arrives, box truck or van with trailer.
T-180. Crew arrives. Unloading begins and the race site starts going up.
T-150. Course crew begins setting the course. For a half marathon or anything longer this moves to T-210 or earlier.
T-120. Timing, AV and packet crews arrive and finalize their stations.
T-105. Water stations delivered and set on course.
T-90. Awards and the athlete experience go in: photo spots, photo booth, distance displays.
Opening and the start: T-60 to the gun
T-60. Race day packet pickup opens, and the course ride-through happens.
T-30. Police on course, volunteers in position.
T-15. First call, corral opens, AV preps for the start.
T-10. Final go from the course team and course security.
T-5. National anthem, then a short briefing.
T-1. Countdown begins.
T-0. Go.
What the shape tells you
Only one thing on this list scales with your race. Course setup moves from T-150 to T-210 or earlier once you go past a 10K, because a longer course is more signage, more marshals and more driving. Almost everything else holds roughly where it is no matter how big the event gets. If you are stretching your timeline for a bigger race, stretch the course window first.
The last hour contains two gates, not two tasks. The ride-through at T-60 and the final go at T-10 are the only two points where somebody confirms the course is actually ready rather than reporting progress on it. Everything before them is work; those two are decisions. Treat them as decisions, and give whoever owns them the authority to say no.
Why T-10 and not T-2. Ten minutes is enough to hold the start, tell the corral why, and fix a small problem. Two minutes is not. The gate is early on purpose, and moving it later to buy setup time is how a five minute delay becomes a twenty minute one.
Tell your timer the gun time
One handoff sits inside T-1 to T-0 and it is the one most likely to be missed: your timer needs the exact moment the gun went. On a staffed event they are standing there and it takes care of itself. On a remote or DIY setup it does not, and a missing start time is the most common cause of a results problem. We cover that in more detail in how remote timing works.
Common questions
Is four hours really necessary for a 5K?For a straightforward 5K on a course you have run before, you can compress the build. What you cannot compress is the order, or the two gates at T-60 and T-10. Most events that start late did not run out of hours, they ran the steps out of sequence.
What changes for a half marathon or longer?Course setup moves to T-210 or earlier, and it usually becomes the first thing that happens rather than something that starts once the site is up. The rest of the morning stays roughly where it is.
What if the course is not ready at T-10?Hold the start and say so. A corral that is told about a five minute delay is fine. A field that is sent onto a course that is not ready is a safety problem, and it is the one mistake on race morning you cannot undo.
When should packet pickup open on race day?We open at T-60. Earlier pulls crew off setup while the site is still going up, and later creates a line that is still moving when the corral needs to fill.
Want us on your start line?We time races across Texas and nationwide, and we have run this morning a few hundred times.
