Kadeena Cox broke her own world record to win gold for ParalympicsGB in the C4-5 500m time trial – just 24 hours after winning athletics bronze.

The 25-year-old became the first British athlete to win medals in multiple sports at the same Paralympic Games for 28 years.

Cox, making her cycling debut at the Paralympics less than a year after her first ever competitive ride, was the last rider to take to the track and produced a stunning time of 35.716, factored to 34.598 to win her first Paralympic gold medal.

Even without factoring, that time would have been enough to give Cox victory – something she had said she was aiming to achieve.

After the race, Cox told Channel 4 that she was stunned by her win.

“I can’t believe it. I’m so happy! I worked so hard for it and my legs were knackered from yesterday. I was mentally fatigued and I wasn’t sure I was going to do it. I did it, I’m over the moon.

“It’s crazy to think of this time two years ago, I had a relapse and I got re-diagnosed, going to hospital.

“To be here now is amazing, I’m just so happy. Doing the two sports is crazy. Taking up cycling and being on top of the world is amazing. I didn’t expect it.”

The result meant Dame Sarah Storey couldn’t win her 13th Paralympic gold, pushing her to fourth, with Crystal Lane taking fifth place.

Storey said: “I’m a pursuiter, I shouldn’t be winning the 500m, it should be won by a sprinter. You can’t ask for better than to be beaten by two world records. That’s what I expected. I’ve been beaten by three sprinters.”

Megan Giglia was the only British rider in action in the first session of the day, competing in the C1-3 500m time trial.

Having already won Paralympic gold in the individual pursuit on Thursday, Giglia went into this event full of confidence and set off at a blistering pace.

The double world champion posted a time of 41.252 to break her own world record, but missed out on a second medal following the factoring of other riders’ times with Dutch rider Alyda Norbruis claiming the gold.

Speaking to Channel 4, Giglia said: “I knew it was going to be hard, some of the C2s put out splendid times, and were faster than me, a well-deserved win for them. For me, it’s about getting faster, they have set the target high for me and I’m going to aim to push myself to be faster and stronger and better next time round.

“I’ve been working really hard, the support of the team has been fantastic and it’s a matter of pushing yourself, you always do find that extra little bit when you’re in competition mode, as long as you’re not scared of crowds that is!”

Louis Rolfe took to the 1km time trial in search of his second Paralympic medal of the Games, but came up against a formidable field.

Rolfe crossed the line in 1:15.788, an improvement on the time that secured him a bronze medal in the C2 1km time trial at the world championships in March.

After factoring, that time was converted to 1:10.582, which placed the Cambridge rider in sixth place.

Gold went to China’s Zhangyu Li in a new world record time of 1:11.937, factored to 1:06.687.
