A Sunday in Hell (original title: En Forårsdag i Helvede) is a 1976 Danish documentary film directed by Jørgen Leth.

Much of the latter portion is over narrow, cobbled tracks that choke with dust on dry days and become slick and muddy in rain.

It begins by introducing the contenders: Eddy Merckx, Roger De Vlaeminck (the previous year's winner), Freddy Maertens, and Francesco Moser, each with their supporting riders (the domestiques), who are charged with helping their team leader win.

The film gives views of the team directors, protesters (the race is halted for a while), spectators, mechanics and riders.

Post-race the exhausted riders, mired in dirt, give interviews in the velodrome's showers.
