Kajsa Tylen cycled over 50,000 km's to break a world record
Kajsa, 40, from Nottingham in the UK, originally from Sweden, took a time off work to go cycling. Over a year later, Kajsa had cycled over 52,025km (32,326 miles) in 12 months, breaking Billie Fleming's 1938 record of 29,604 miles (47,642 km).
She says she took on the challenge to inspire people to do more exercise and has since cycled every day across England and parts of mainland Europe, battling through illness, bad weather and physical pain to break the record.
In Scandinavia, in the summer, she rode through the night while the sun was still visible, an experience she described as "spectacular". Kajsa said: "It's not sunk in yet and I don't think it ever will it's a such a ridiculously big number to have ridden, "I always knew I'd finish it unless I got injured or ill, but sometimes I wanted to pack it all in".
"I had to write event logs and I've got notes on the back on them and on some I've just written "why am I doing this?".
Her achievement is expected to be verified with Guinness World Records at a later date.
