For a man that gets sweaty just walking up the stairs, this is going to be interesting. I've also been informed that flip flops don't class as 'suitable footwear'...... :)

Details of the challenge.....

Colleagues across Group Technology in Barclays are taking place in a full marathon walking challenge to raise funds for Maggie's Centres.

Built in the grounds of 24 NHS cancer hospitals, Maggie’s offers free practical, psychological and financial support to people with cancer and their families and friends. We deliver over 350,000 sessions of support each year. Our centres are designed to be more like a home than a hospital, providing a calm and friendly place where people with cancer can find the hope, determination and resources they need to cope with one of the toughest challenges any of us is likely to have to face.
