Richie Porte's hopes of winning the 98th edition of the Giro d'Italia have sufffered a massive blow after the Team Sky rider lost three quarters of a minute to Tinkoff-Saxo's Alberto Contador – and then had a further 2 minutes docked by commissaires, who said he had received illegal assistance from Orica-GreenEdge's Simon Clarke.

Porte's fellow Australian, who spent last Wednesday in the race leader's maglia rosa, stopped to give Porte his front wheel after his compatriot punctured with around 10km to go in today's 200km stage from Civitanova Marche to Forli, won from the break by Bardiani-CSF's Nicola Boem.

However well intentioned that gesture was, it has cost Porte dear. While professional cycling throughout its history has been characterised by alliances between teams – sometimes to help thwart a common rival, other times to ensure a break stays away – such a flagrant disregard for the rules was not going to go unnoticed.

Porte began the day 22 seconds behind race leader Alberto Contador of Tinkoff-Saxo, and despite his Team Sky colleagues attempting to get him back to the peloton, lost 47 seconds on the line.

Initially, it was unclear why commissaires had blocked the convoy of team cars from going through, which prevented Porte from getting assistance from Sky mechanics and being able to get a helpful tow from friendly sports directors, as would typically happen.

However, it now seems clear why race officials decided to prevent that happening.

Porte now lies 12th overall, 3 minutes 9 seconds down on Contador – and 39 behind his own team mate, Leopold Koenig.

Spanish journalist Laura Meseguer tweeted pictures of the incident.

 

 

Fellow professionals – current and retired – were quick to rally round Porte and Clarke, who also loses 2 minutes, on Twitter.

 

 

The Giant-Alpecin rider was clearly unaware of what the commissaires thought of the incident when he tweeted that; later, he added:

 

 

Other riders chipped in too.

 

 

 

 

UCI rule 2.3.012 about the 'Rights and Duties of Riders' is very clear, however:

All riders may render each other such minor services as lending or exchanging food, drink, spanners or accessories.

The lending or exchanging of tubular tyres or bicycles and waiting for a rider who has been dropped or involved in an accident shall be permitted only amongst riders of the same team, The pushing of a rider by another shall in all cases be forbidden, on pain of disqualification.

One interpretation of the final part of that rule is that both Porte and Clarke are lucky they are still in the race.

Sky principal Sir Dave Brailsford, quoted on the team's website, said: "It is obviously disappointing that a sporting gesture made in the heat of the moment has resulted in such a strong penalty. No one was trying to gain an unfair advantage.

"This has however just strengthened our resolve and determination to fight for this race. Richie and the whole team are ready to take it on and there is a lot of this Giro left."
