The inaugural Marbella Ironman 70.3 took place on Sunday 28th April 2018. The race has taken place every year since then except 2020. The race always takes place on a Sunday in Spring or Autumn but the date varies.

There are actually about 30 triathlon events every year in Andalucia, which are held between February and November, including during the hot summer months. Desafio Doñana is the flagship event organised by the sports agency of the regional government. Others take place in locations in western and central Andalucian coastal areas.

The third edition of the Andalucía Desafío Doñana (Andalucia Doñana Challenge) triathlon took place on Saturday 17 September 2011.
