Denise Mueller has gone faster than anyone has ever been on a bike! Eight years ago on Bonneville Salt Flats in Utah, she travelled at an average of more than 183 mph, smashing the previous record and setting the mark that still stands today. What makes Denise's story even more remarkable is that she took a 20 year break from cycling before returning in her 40's to break the record. From her home in San Diego she took us back to where it all started, aged 14 when her grandfather bought both her and her dad a bike
