The 2015 Ruta del Sol ended in Alhaurin de la Torre with Juan José Lobato besting John Degenkolb by 1 second on the uphill arrival. The GC was already pocketed by Chris Froome, two seconds ahead of Alberto Contador.
The explosive 15% section in the individual time trial lies west of Alhaurin de la Torre on the Camino de Comendador. The climb begins with around 5 kilometres done and lasts until kilometre 6. After the drop the race continues on rolling roads, while the finish is uphill after a 5.5% climb in the final 600 metres.
Last year, the chrono race in the Vuelta a Andalucia was won by Javier Moreno.
Alhaurin de la Torre is an ancient town, founded in 1,000 BC by the Phoenicians.
