What are the road races, and how are they won?
B · Beginner · The event · 1 of 4A road race is run on roads over a measured course. The winner is the first athlete whose torso reaches the finish line. The standard distances run from the road mile to 100 km and include the half marathon and the marathon, which is 42.195 km. Times are taken from the gun and recorded to the whole second.
How it works
- The distances: "Road Mile (1609.344m), 5km, 10km, 15km, 10 Miles, 20km, Half-Marathon, 25km, 30km, Marathon (42.195km), 50km, 100km and Road Relay."
- The surface: made-up roads.
- The course: measured in advance along the shortest route a runner could take, and never shorter than the stated distance.
- The start: a standing start behind a line, to a gun, cannon, air horn or similar signal.
- Water: available at the start and finish and about every 5 km. In races longer than 10 km other refreshments may be offered as well.
- Staying on the course: a runner who leaves the marked course and shortens the distance is disqualified.
- The finish: athletes are placed in the order their torsos reach the finish line.
- The time: from the gun to the finish, recorded to the next whole second.
- Records: a course must meet extra conditions before a time on it can be a record.
Tricky cases
Is every marathon exactly the same distance?
No, not exactly. A course may not be shorter than 42.195 km, and courses are laid out very slightly long to make sure of that.
Is a 10 km on the road the same event as a 10,000 m on the track?
No. They are separate events with separate records. The road race is recorded to the whole second and the track race to a hundredth.
Do the rules apply to everyone in a big city marathon?
No, not in full. The rule book says that in mass events the rules should normally be applied in full only to the elite field and other sections racing for placings or prizes. Organisers tell the other runners which rules apply to them.
Why the rule exists
No two road courses are the same, so the rules fix what can be fixed: the distance, how it is measured, what help runners may have and how they are timed. That is what lets a marathon in one city be compared with a marathon in another.
