Peter Sagan’s challenge in the Olympic mountain bike race in Rio came was hit early on by a puncture after the road world champion had made a huge charge early on to move up from last place on the starting grid to get in touch with the leaders including eventual winner Nino Schurter of Switzerland.

It was the first of two flats this afternoon for Sagan, who had decided to try and get a place in the event after concluding earlier this year that the road race course would be too difficult for him following a reconnaissance ride.

The puncture came at the end of the first of seven 4.7km laps, the second coming towards the end of the race and resulting in the Slovak rider abandoning.

Eight years ago five-time world champion Schurter took bronze in Beijing and was runner-up in London four years ago when he was outsprinted to the line by Jaroslav Kulhavy of the Czech Republic, who turned out to be his closest rival today, the pair swapping the lead until riding away with a lap and a half left.

Spain’s Carlos Coloma was third but just as happened at London 2012, French legend Julien Absalon, riding the Olympics for the last time, fell out of contention due to a puncture early on.

Sagan wrote on Facebook afterwards: “This is mountain biking, technical problems can happen and stop me. I started well, but two punctures ruined my race.

“I think I would not be able to stay in front with the best riders today, but maybe I could get a much better position.

“After the first puncture, I managed again to get to 11th place, but after the second I could not,” he added.
