Sign up for a sponsored walk around Queen Elizabeth Olympic Park this weekend to raise money for charity. The Macmillan Mighty Hike offers 13- —or 27-mile routes through the park, along the picturesque marshes, and out into leafy Epping Forest.
There's a £250 per person fundraising pledge, which goes to Macmillan's work supporting people living with cancer. The event commences at 7.30 am.
