The men's 4 × 100 metres relay event at the 1986 Commonwealth Games was held on 2 August at the Meadowbank Stadium in Edinburgh.
The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each. The first runners must begin in the same stagger as for the individual 400 m race. A relay baton is carried by each runner. Prior to 2018, the baton had to be passed within a 20 m changeover box, preceded by a 10-metre acceleration zone. With a rule change effective November 1, 2017 that zone was modified to include the acceleration zone as part of the passing zone, making the entire zone 30 metres in length. The outgoing runner cannot touch the baton until it has entered the zone, the incoming runner cannot touch the baton after it has left the zone. The zone is usually marked in yellow, frequently using lines, triangles or chevrons. While the rule book specifies the exact positioning of the marks, the colors and style are only "recommended". While most legacy tracks will still have the older markings, the rule change still uses existing marks. Not all governing body jurisdictions have adopted the rule change.
At the 1986 Commonwealth Games, the athletics events were held at the Meadowbank Stadium in Edinburgh, Scotland. A total of 41 events were contested, of which 23 by male and 18 by female athletes.
Meadowbank Stadium was a multi-purpose sports facility located in the Meadowbank area of Edinburgh, Scotland. Built on the site of the earlier New Meadowbank and Old Meadowbank sports venues, it was originally built to host the 1970 Commonwealth Games. It also hosted the Games in 1986, becoming the first venue to host the Games twice.
