Knud Enemark Jensen (30 November 1936 – 26 August 1960) was a Danish cyclist who died while participating in the 1960 Summer Olympics in Rome, Italy. He is notable for having been involved in an early doping scandal.
The Olympic 100 km team time trial road race was held in over 100-degree heat on Viale Cristoforo Colombo in Rome. One of the four-man Danish team, Jorgen B. Jorgensen, dropped out of the race due to sunstroke after the first lap, necessitating that all three remaining Danish cyclists finish the race for the team not to be disqualified. Jensen told his teammates that he felt dizzy. Niels Baunsof clutched his jersey, keeping him from falling, while Vagn Bangsborg held Jensen from the other side. Bangsborg sprayed Jensen with water, leading to an apparent improvement, but when Baunsof let go, Jensen collapsed and fractured his skull on the pavement.
Jensen was brought by ambulance to an overheated military tent near the finish line, where he died that afternoon without regaining consciousness. Prince Axel of Denmark, an International Olympic Committee member, was on his way to Jensen's bedside when Jensen died.
