But after taking ill last night and still managing to break the 12 hour record around midnight, Sharon continued until 4am this morning, when she was forced to call it a day.
Sharon, who has been supported by staff from the University鈥檚 School of Social Sciences, Business & Law during her run, said: 'I started to feel sick around 9pm but wanted to keep going to at least set one record, which I managed to break at midnight. I took a short break and was able to continue one until 4am, but I just wasn鈥檛 able to recover from the sickness.
'I鈥檓 bitterly disappointed, but at least it鈥檚 better to have at least set one record and achieve something.'
The part-time lecturer at 海角直播 made headlines in 2011 when she spent seven days on a treadmill, smashing both the men鈥檚 and women鈥檚 world records and covering a total distance of 833.05km or 517.63 miles. That record is yet to be beaten.
During her career Sharon has run over 300 marathons and 100 ultra-distance races, including the Badwater Ultramarathon of 135 miles across Death Valley 鈥� billed as the hottest race on earth. In 2009 she won a gold medal at the Commonwealth Championships 24 hour event.
She added: 'I鈥檓 grateful to 海角直播 for once again showing me incredible support, they鈥檝e been brilliant, absolutely faultless.'
Keith Haley, from the University's School of Social Sciences, Business & Law, said: 'We are always happy to offer support to Sharon and we congratulate her on her latest achievement.'
