Do-gooders seeking a new challenge have been urged to sign up to Cancer Research UK’s Tough 10.

On October 21 the ancient woodlands of Epping Forest will be turned into a 10km long track of muddy trails, steep hills and uneven terrain.

The charity’s Tough 10 series is chip timed enabling runners to see how quickly they have completed the challenge.

The meeting point is on Bury Road, close to Chingford Station.

Money raised will help Cancer Research UK in its life saving work.

Dearbhla Cormacain, event manager, said: “This is a tough challenge over 10k of root-laden, uneven trails cutting through the forest and countryside but we know local runners have got what it takes to tackle Tough 10 and we’re delighted to be hosting the event again.

“Every day, around 90 people in the region are diagnosed with cancer. That’s why we need as many people as possible to double knot their trainers and take on our stamina-testing course.

“If the steep inclines don’t take participants’ breath away, the stunning views and scenery will, along with the knowledge that every stride they take will help bring us closer to beating cancer sooner.”
