I WANTED to let you know about Macmillan Cancer Relief's fantastic charity challenges taking place in the autumn in the exotic countries of Costa Rica and Ecuador.

Your challenge is to walk or cycle for seven days, for an average of eight hours per day, through some of the toughest but most beautiful terrain imaginable, raising money to help Macmillan's cancer care services.

Macmillan's challenge is to support people living with cancer all over the country.

Think you're up to it? Sign up now. Call 0845 604 3601 to find out more.

Money you raise will really make a difference to people living with cancer in the UK.
