AMSTERDAM (AP) — Dutch cyclist Robert Gesink says he has a heart rhythm problem and will temporarily stop racing to seek treatment.
The Belkin rider said Tuesday the cardiac arrhythmia hit him hard after a mountain climb during last year's the Giro d'Italia, leaving him hyperventilating and afraid. He decided he would seek treatment if it happened again.
He says that the problem struck again last Friday in the Tour of the Basque Country.
Gesink says he aims to "recover completely and return to the highest level" of cycling.
The 27-year-old has long been seen as a talented rider, but has yet to win a major tour stage or spring classic. He was fifth in the 2010 Tour de France and has three top-10 finishes in the Vuelta.
