Six Day races can be stage events where the entrants run between certain hours for each day and then regroup at night, ready for the next day. A Six day race can also be from point to point.

This event is a circuit race, meaning that the entire distance takes place on a circuit, in this case a 1000m (1km) track. Some events use a 400m track which allows for world records to be recognised if the event is an IAAF certified race.
Although we don't expect a lot of world record times, every lap is timed (and counted). Finishing criteria vary from event to event.
A minimum distance of 403km (250 miles) is required for the George Archer 6 Day. In 1995, the minimum distance was 400km which translated to a messy 248 point something miles so it was rounded up for future events to 403km which equates to 250 miles.

It is also known as a go-as-you-please event. You are free to run/walk/sleep/eat etc at any time during the 144 hours.
24 hour periods will be measured from 15:00 until 15:00 on the following day. If the race starts late for some reason e.g 15:20, then the 24 hour period is taken from 15:20 until 15:20.
These 24 hour periods are used to determine the daily distances.

Unlike some overseas races, there is no minimum daily distance to be covered on each day. In the unlikely event that you are able to finish 403km on day 1, you are entitled to put your feet up for the next 5 days of the week.
Equally, should you get carried away by the excitement and country air on Day 1 and completely overdo it, you can rest for part of Day 2 without getting thrown out of the race.

Some athletes bring their whole family along, others leave the family at home. Traditionally, each participant seconds themselves from their campsite which is situated alongside the track. Many runners/walkers work solo without additional people although this is not recommended where you are planning to win and every second is counting.
