Two friends from Northchurch are tackling the 100km Race To The Stones this weekend to raise money for the charity that is caring for one of their brothers.
The event takes runners from Chinnor to Compton on Saturday, and from Compton to the neolithic Avebury stone circles on Sunday.
Andrew Gifford, 38, and Mike Kazer, 28, are taking part to raise money for Macmillan Cancer Support, which is supporting Andrew’s brother, Dave.
Dave is now going through chemotherapy for a 16-centimetre cancerous tumour on his kidney.
Andrew said: “Dave’s 35, with two young children, never smoked, and has always been fit, so it just hits home it could be anyone of us facing this horrible fight.”
