Cross de los Dolores is a cross-country race series held in Cartagena, within Spain's Murcia region. The main events begin in the morning in late November. It is also known as the Trofeo Presidenta de Campo a Través UCAM Cartagena. The race is organized by UCAM's sports service, with assistance from Cartagena City Council.
The format features several short off-road races instead of a single distance. Younger participants compete on courses starting around 1.4 km. Older youth races cover distances of approximately 2.2 km, 2.8 km, and 3.5 km. The adult races include a military event just under 4.9 km, and university, vocational-training, and popular races around 4.7 km. The 4.7 km popular race is designated as non-competitive. Having been held for multiple editions, the event is established as a local athletics fixture, with school-age runners, university students, military personnel, and casual runners participating in the same cross-country program.
