Dumoulin survives untimely call of nature as Nibali wins

Updated: 

Tom Dumoulin survived an untimely call of nature to hold on to the lead of the Giro d'Italia as Vincezno Nibali claimed a narrow stage 16 victory ahead of Mikel Landa.

Dumoulin went into Tuesday's 222-kilometre ride from Rovetta to Bormio with a lead of two minutes and 41 seconds over his nearest challenger Nairo Quintana (Movistar).

But the Sunweb rider's hopes looked set to be dealt a significant and unusual blow as he was forced to pull over to a stop and strip down his kit to relieve apparent stomach discomfort with 33km remaining.

That stoppage saw the general classification group, featuring Quintana, Nibali (Bahrain - Merida) and Thibaut Pinot (FDJ) gain significant time on the Dutchman.

Nibali eventually caught Team Sky rider Landa, the sole survivor of a break that had featured more than 20 riders, with 10km left, and that pair had a lead of more than three minutes over Dumoulin at one point.

But, as Nibali edged Landa in a sprint to the line, Dumoulin recovered to come home just two minutes and 18 seconds down.

Quintana finished third - 12 seconds off the pace - giving Dumoulin a lead of 31 seconds in the overall standings after an extremely trying day.

"I just had problems, I needed to take a dump - I couldn't hold it anymore," Dumoulin said. "It was after the Stelvio [second climb] I began to feel it in the downhill. I had to stop, it was not possible to continue anymore.

"I had to fight and fight and fight, and take conclusions after the finish. That's what I did. I'm very disappointed."

GOOD DAY / BAD DAY

Though he did not claim the stage victory, Landa received ample reward for his magnificent efforts. The Spaniard earned the Cima Coppi prize for topping the highest peak in the Giro - the Passo dello Stelvio - and was also first up the final ascent to claim maximum King of the Mountains points and the climber's jersey before being caught by Nibali on the descent.

The Cipo Scarponi prize, named after Astana rider Michele Scarponi who was tragically killed in training for the Giro, went to his former team-mate Luis Leon Sanchez for cresting the summit of the first climb, the Passo del Mortirolo

Dumoulin may have kept hold of the Maglia Rosa, but his advantage has been cut significantly and he will need to recover quickly from any ailment ahead of stage 17 on Wednesday.
