Kenenisa Bekele Beyecha is an Ethiopian long-distance runner. He was the world record holder in both the 5,000-metre and 10,000-metre from 2004 until 2020. He won the gold medal in both the 5,000 m and 10,000 m events at the 2008 Beijing Olympics. At the 2004 Olympics, he won the gold medal in the 10,000 m and the silver medal in the 5,000 m.
A pacemaker or pacesetter, sometimes informally called a rabbit, is a runner who leads a middle- or long-distance running event for the first section to ensure a high speed and to avoid excessive tactical racing. Pacemakers are frequently employed by race organisers for world record attempts with specific instructions for lap times. Some athletes have essentially become professional pacemakers. A competitor who chooses the tactic of leading in order to win is called a front-runner rather than a pacemaker.
Eliud Kipchoge is a Kenyan long-distance runner who competes in the marathon and formerly specialized in the 5000 metres. Kipchoge is the 2016 and 2020 Olympic marathon champion, and was the world record holder in the marathon from 2018 to 2023, until that record was broken by Kelvin Kiptum at the 2023 Chicago Marathon. Kipchoge has run four of the 10 fastest marathons in history.
Running economy (RE) a complex, multifactorial concept that represents the sum of metabolic, cardiorespiratory, biomechanical and neuromuscular efficiency during running. Oxygen consumption (VO2) is the most commonly used method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects energy metabolism. Those who are able to consume less oxygen while running at a given velocity are said to have a better running economy. However, straightforward oxygen usage does not account for whether the body is metabolising lipids or carbohydrates, which produce different amounts of energy per unit of oxygen; as such, accurate measurements of running economy must use O2 and CO2 data to estimate the calorific content of the substrate that the oxygen is being used to respire.
Lelisa Desisa Benti is a retired Ethiopian long-distance runner who specialises in road running competitions. Desisa gained his first international medal at the 2009 African Junior Athletics Championships, where he took the 10,000 metres gold medal.
A negative split is a racing strategy that involves completing the second half of a race faster than the first half. It is defined by the intentional setting of a slower initial pace, followed by a gradual or sudden increase of speed towards the end of the race. Alternate strategies include even splitting or sit and kick. Conversely, the act of completing the first half of a race faster than the second half is known as a positive split.

American Daniel Romanchuk won the men's wheelchair title in 1:33:38 while Switzerland's Manuela Schär won the women's title in 1:44:09. Changes were made to the course to make it more environmentally friendly; the number of plastic bottles used was reduced and biodegradable alternatives were used instead.
The men's marathon event at the 2020 Summer Olympics started at 07:00 on 8 August 2021 in Sapporo, Japan. 106 athletes from 46 nations competed. The previous Olympic champion, Kenyan Eliud Kipchoge, successfully defended his title, with Dutch and Belgian athletes Abdi Nageeye and Bashir Abdi gaining silver and bronze, respectively.

The Ineos 1:59 Challenge, held on 12 October 2019, was an attempt by Kenyan athlete Eliud Kipchoge to break the two-hour mark for running the marathon distance, which he achieved in a time of 1:59:40.2. The event was specifically created for Kipchoge and held in Vienna, Austria to help market the Nike ZoomX Vaporfly 4%. Kipchoge had previously attempted to run a two hour marathon at the Breaking2 event organised by Nike in 2017, but he fell short by 25 seconds.
