The men's individual road race event at the 2020 Summer Olympics took place on 24 July 2021 on a course starting at Musashinonomori Park in Tokyo, and ending at the Fuji Speedway in Shizuoka Prefecture. 128 cyclists from 57 nations competed, with 85 completing the course.
 The race was won by Richard Carapaz of Ecuador. Carapaz, along with Brandon McNulty of the United States, attacked with 25 kilometres (16 mi) to go and immediately built a gap over the chasing group. Both riders worked together until Carapaz dropped McNulty with 5.8 kilometres (3.6 mi) to go. Carapaz held off the chase group to win the race by more than a minute. The silver and bronze medals went to Wout van Aert of Belgium and Tadej Pogačar of Slovenia, respectively. Both riders were part of the 11-man chase group that rode in pursuit of Carapaz and McNulty. Eight of the 11 riders contested the sprint for the silver medal, with van Aert holding off Pogačar to take second.
 This was the 21st appearance of the event, initially held in 1896 and then at every Summer Olympics since 1936. It replaced the individual time trial event that had been held from 1912 to 1932; the time trial was re-introduced in 1996 alongside the road race.
 A National Olympic Committee (NOC) could enter up to five qualified cyclists in the men's individual road race. All quota places are assigned to the NOC, which may select the cyclists that compete. There were 130 total quota spots available for the race, which were allocated in a multi-step process:
 Finally, both Simon Geschke of Germany and Michal Schlegel of the Czech Republic did not start the race after testing positive for COVID-19 the day before the race.
 The road race was a mass-start, one-day road race event. The courses for the men's and women's road races were revealed in August 2018. The men's race started at Musashinonomori Park in Chōfu, western Tokyo, at 11:00 Japan Standard Time (UTC+9) and finished at the Fuji Speedway circuit in the Shizuoka prefecture. The race was 234 kilometres (145 mi) long with a total elevation gain of 4,865 metres (15,961 ft).
 The first part of the men's and women's races were identical. The course first passed through the mostly flat outskirts of Tokyo's metropolitan area. After 40 kilometres (25 mi), the riders gradually climbed towards the foot of the climb to Doushi Road, a 5.9-kilometre (3.7 mi) climb with an average gradient of 5.7 percent. The climb topped out after 80 kilometres (50 mi) of racing at an altitude of 1,121 metres (3,678 ft) above sea level. After reaching Lake Yamanakako in Yamanashi and crossing the Kagosaka Pass, the riders faced a 15-kilometre (9.3 mi) descent and from here, the courses were different for the men's and women's races.
 After the descent, the men's race headed towards the lower slopes of Mount Fuji, Japan's highest mountain, where they went up the 14.3-kilometre (8.9 mi) long climb of Fuji Sanroku with an average incline of six percent. The climb was crested with 96.5 kilometres (60.0 mi) left at an elevation of 1,451 metres (4,760 ft) before the riders faced a 15.5-kilometre (9.6 mi) long descent into Gotemba. Afterwards, the riders headed towards the Fuji Speedway section, where they crossed the finish line twice before reaching the foot of the Mikuni Pass. The climb was 6.5 kilometres (4.0 mi) long with an average gradient of 10.6 percent and included sections reaching 20 percent. It was expected to be the decisive climb in the race. The peak, at an altitude of 1,171 metres (3,842 ft), was crested with about 33 kilometres (21 mi) to go. After the climb, the race returned to Lake Yamanakako and the Kagosaka Pass before a final descent and a short hilly section towards the finish on the Fuji Speedway circuit.
 Nations:
 As soon as the race started, a group of eight riders broke away from the peloton. The group comprised Nicholas Dlamini (South Africa), Michael Kukrle (Czech Republic), Juraj Sagan (Slovakia), Polychronis Tzortzakis (Greece), Eduard-Michael Grosu (Romania), Orluis Aular (Venezuela), Paul Daumont (Burkina Faso), and Elchin Asadov (Azerbaijan). The break reached a maximum advantage of around 19 minutes before the peloton began its pursuit, with defending Olympic champion Greg Van Avermaet (Belgium) and Jan Tratnik (Slovenia), in particular, leading the chase. On the gradual uphill section ahead of the climb to Doushi Road, Tristan de Lange (Namibia) attacked from the peloton but he was eventually caught. With around 150 kilometres (93 mi) to go, a crash took place in the peloton, taking down the Great Britain duo of Geraint Thomas and Tao Geoghegan Hart as well as Giulio Ciccone (Italy) and Gregor Mühlberger (Austria). All riders eventually managed to get back up and return to the peloton. Up front, the break was reduced to five riders – Aular, Dlamini, Tzortzakis, Kukrle, and Sagan – after the first climb. The group led the peloton by around 16 minutes.
 As the race reached the foot of Fuji Sanroku, Van Avermaet and Tratnik continued to lead the chase as the break started the climb with a lead of around 13+1⁄2 minutes. Patrick Bevin (New Zealand) went to the front to help with the chase and the break's lead gradually decreased as the climb went on while further up the ascent, Van Avermaet began to get dropped along with several other riders. Near the top, Ciccone took over at the front of the peloton to set a faster tempo. Some of the notable riders to struggle on the climb include the Spanish duo of Omar Fraile and Alejandro Valverde. The break reached the top of Fuji Sanroku with a lead of almost six minutes. Tratnik soon made his way back to the front of the peloton to gradually eat into the break's advantage, with the break reaching the Fuji Speedway with a lead of around four minutes. At the start of the circuit, several riders began to abandon the race, most notably Thomas, Van Avermaet and Fraile.
 After the first passage through the finish line, attacks lit up the peloton as Damiano Caruso (Italy), Wilco Kelderman (Netherlands), and Mauri Vansevenant (Belgium) rode away. After the three riders were caught, Remco Evenepoel (Belgium) instigated another attack and brought Vincenzo Nibali (Italy) and Eddie Dunbar (Ireland) with him. Meanwhile, up front, the break began to splinter as Sagan and Dlamini couldn't continue with the quick pace and the peloton edged closer to them. The trio of Evenepoel, Nibali, and Dunbar was soon brought back. As the race reached the Fuji Speedway for the second time, the remnants of the original break were finally caught, with the peloton setting themselves up for the decisive climb of the race, the Mikuni Pass.
 As the peloton reached the foot of the Mikuni Pass, Italy stationed themselves up front before Tiesj Benoot (Belgium) began to set a furious pace. After Benoot's work was done, his compatriot Vansevenant continued to set a fast tempo as the peloton continued to thin out. With around 37.4 kilometres (23.2 mi) to go, Tadej Pogačar (Slovenia) put in a seated[clarification needed] acceleration. Brandon McNulty (United States) and Michael Woods (Canada) followed his move while Wout van Aert (Belgium) led the chase group. The trio led by around 20 seconds before riders began to bridge up front. Near the top, the front group struggled with cooperation as the group including van Aert managed to make it across. As the group made its way back to Lake Yamanakako and the Kagosaka Pass, several riders attacked off the front. Bauke Mollema (Netherlands) and Jakob Fuglsang (Denmark) tried to initiate some attacks but the moves were brought back.
 With 25 kilometres (16 mi) to go, Brandon McNulty accelerated off the front with Richard Carapaz (Ecuador) responding to the move. The duo began to increase their advantage as the chase group suffered from a lack of cooperation, with van Aert leading much of the chase. The duo's advantage reached more than 40 seconds before van Aert produced a searing acceleration on a short uphill rise with around 12 kilometres (7.5 mi) to go. The lead was soon down to 13 seconds with 7 kilometres (4.3 mi) to go. With 5.8 kilometres (3.6 mi) left, Carapaz dropped McNulty to solo off the front. After McNulty was caught by the chase group, the riders continued to attack each other, allowing Carapaz to increase his lead once again. Carapaz would not be caught as he won the gold medal, his country's second in history. With gold already taken, the chase group set themselves up for the sprint for the silver and bronze medals, resulting in an 8-way race for the finish in the final metres of the race, which was initiated by Adam Yates (Great Britain). Van Aert and Pogačar prevailed in the sprint, taking silver and bronze respectively. The gap between second and ninth places was within a single second.
