Hello.  So David and I are going to run 10k (each) in aid of this brilliant organisation who are using the money to support women in war-ravaged DRC (Congo).  Providing them with training and resources to rebuild their lives and support themselves and their families. And here's the official blurb about giving money on this website:

Donating through JustGiving is simple, fast and totally secure. Your details are safe with JustGiving – they’ll never sell them on or send unwanted emails. Once you donate, they’ll send your money directly to the charity and make sure Gift Aid is reclaimed on every eligible donation by a UK taxpayer. So it’s the most efficient way to donate - I raise more, whilst saving time and cutting costs for the charity.
