Triathlon is a sport is a combined sport divided into three segments: swimming, cycling and running. Distances can range from 350m swimming, 10km cycling and 2.5km running (super-sprint) all the way up to the mythical 3.8km swim, 180km cycling and 42.2km running (ironman). The Olympic distances are 1.5km swimming, 40km cycling and 10km running.
The first Triathlon event in Portugal took place in Peniche on the 15th of August 1984 and the sport has gone on to attract a lot of attention and investment.
Sporting's first probe into the sport came in the 1980's, however it wasn't until 2009 that it really took off with the help of a dynamic project. Taking into account the huge importance of swimming as part of Triathlon and Sporting's success in the pool, the sport and Alvalade go hand in hand. João Curado is the first example of a transition from swimming into Triathlon at the club, resulting in an international call up in 2009.
In 2010, the popularity of the sport at Alvalade saw the creation of a Triathlon School, with the goal of training not only top athletes, but also those who enjoy the sport. That season, Sporting claimed two podium sports in the Under-23 National Championship courtesy of Rúben Costa and Diogo Tarelho, while Rodrigo Baltazar won the European Championships in the 30-34 age group.
