The Half-Distance race, held on 19th May, will include a mountain section during the cycling segment.
The organisers say this will help to avoid drafting issues as well as encourage a larger number of triathletes to compete.
The cycling segment will be a continuous 90km lap, and the added mountain route will incorporate an accumulated climb of 1000m which will also offer competitors some spectacular views.
Race Director Agustí Pérez said: “When we get to the 90 km cycling segment, the triathletes will be able to enjoy some unique scenery as they pass through inland towns on the mountainsides.
“It will consist of a single lap and a total accumulated climb of more than 1,000 metres, which will avoid drafting and also offer the chance to enjoy some unbeatable views over two natural parks, Monsteny and Collsacreu.”
Challenge Barcelona-Maresme also confirmed that, with three months until the race, there are more than 1,500 registered entrants and they hope to break the 2,000 barrier come May.
