If you’ve never seen people “zorbing” down sharp inclines in giant transparent balls, tomorrow’s your chance, as scores of brave participants take part in a fundraiser for Kiya, a UK charity that helps special needs children in Peru.

Kiya has teamed up with “zorbing” specialists Orb360 to launch The Big Roll. Those who have raised the necessary £100 sponsorship money will spin head over heels down the half-mile run at speeds of up to 30mph. Onlookers can watch from the “Orb-Shack”, where there will be music, a barbecue and refreshments.

* From noon-4pm. Participants must raise £100 in sponsorship to take part. Call 01273 721092
