Cyclist Daan Myngheer has died in hospital after suffering a heart attack on Saturday during the first stage of the Criterium International in Corsica.
He is the second Belgian cyclist to die in as many days after Antoine Demoitie was struck by a motorbike during Belgium’s Gent-Wevelgem race.
Myngheer, 22, who turned professional last year, had been in an induced coma.
His team, Roubaix Metropole Lille, said in a statement: “He lost his last race after fighting like a champion.”
Myngheer pulled up in difficulty 20 miles from the line in the first stage of the race at Porto-Vecchio on Saturday.
He suffered the heart attack while in an ambulance, before being transferred by helicopter to hospital, where he was put on artificial respiration and fell into a coma.
The tragedy came after Demoitie, 25, was killed on Monday after being hit by a motorbike when several riders came down in a crash as they passed through northern France during Sunday’s Gent-Wevelgem one-day race.
Demoitie, who was riding for the Wanty-Gobert team, was taken to hospital in Lille but died some time later.
In January, six racers from the Giant-Alpecin team, including German John Degenkolb and Frenchman Warren Barguil, were injured in a collision with a car during a training ride south of Valencia.
