AFTER donning an orange morph suit, an Oxford woman toured all of the capital's underground stations in just over 18 hours to raise money for charity.

Natasha Medlock, from Littlemore, put on the luminous costume as she and five other colleagues visited all 270 stations in support of Stand Up To Cancer.

The 37-year-old was inspired to take on the challenge in memory of her nan, Clarice Howley, who died of a brain tumour and lung cancer when she was 15.

Despite admitting her nan would have hated the idea of her wearing the bright suit, Ms Medlock said the donations made it all worthwhile.

The business systems manager, said: "Although I lost her a long time ago, it is my main reason for working with Cancer Research UK and it really focused my fundraising efforts during this challenge.

"She would have hated the thought of it.

"Being together as a team and all the social media support we had throughout the day was fantastic.

"Seeing the donations rising made us feel like we were achieving something."

Ms Medlock set off with the group from Heathrow at 5.15am on Thursday, October 20 and completed their journey at 11.34pm at Uxbridge.

Jokers Masquerade donated the morph suits for the six team members.

The joint fundraising campaign from Cancer Research UK and Channel 4, Stand Up To Cancer aims to raise money to fund translational research, which takes developments in the lab and transforms them into brand new tests and treatments for cancer patients.

Currently the team have raised £1,750 but they were unable to beat the current world record for visiting all the underground stations in a day.

The current world record stands at 15 hours 45 minutes and 38 seconds and Ms Medlock and her colleagues' efforts came in at a time of 18 hours 23 minutes.

Emily Attwood, from Cancer Research UK, said: "We would like to thank Natasha and her team mates for standing out in the fight against cancer.

"Stand Up To Cancer aims to accelerate the translation of brilliant scientific discoveries into innovative cancer medicine, tests and treatments.

"Every pound raised will help to support this progress and bring forward the day when all cancers are cured."

The fundraising campaign is endorsed by a host of celebrities, and this year on the Channel 4's Friday night programme, hosted by Davina McCall and Alan Carr, more than £15.7million was raised.

The campaign first came to fruition in 2008 in America before coming to the UK and Channel 4 in 2012.
