An ecstatic Jody Cundy helped Great Britain overcome adversity as he topped another world championships podium.

Cundy, who retained his kilo crown at the 2016 UCI Para-Cycling Track World Championships on Thursday, won his second gold in the mixed team sprint today. GB's success was even more stunning after Louis Rolfe was forced to replace Kadeena Cox after she was ruled out when the severity of her her multiple sclerosis impairment was downgraded.

'We rode that team at the national championships in September (2015) and we did 51.4 (secs),' Cundy told British Cycling.

'We've just done 49.2(30). It's just phenomenal to take off that much time. For Louis to step in as well at the last minute, we've been training with Kadeena as our 'man one' for the last couple of weeks but she got reclassified, and we'd done no practice with him.

'We knocked it out of the park. We did a 50.1 in the morning which qualified us fastest, which was a surprise, and then to go nearly a second quicker than that in the afternoon was outstanding. Gold medal, world record, can't really complain.'
