Sara Dossena is an Italian long-distance runner, who won a gold medal at the 2018 Mediterranean Games. She also won three national championships. In 2019, she competed in the women's marathon at the 2019 World Athletics Championships held in Doha, Qatar. She did not finish her race.

The women's marathon was one of the road events at the 2019 World Athletics Championships in Doha, Qatar. Due to the heat in Doha, the race was scheduled to begin at 23:59 on 27 September 2019, which made it the first midnight marathon in the history of the World Championships. Even with the unusual timing, the temperature was above 30 °C (86 °F) and the humidity over 70 per cent, making conditions difficult for running. Only 40 of the 68 entrants finished the race, which was won by Ruth Chepng'etich of Kenya in 2:32.43; the slowest winning time at the World Championships. Bahrain's Rose Chelimo was second in 2:33.46, with Helalia Johannes of Namibia third in 2:34.15.
