A MAMMOTH non-stop relay marathon is passing through Cornwall during a world record attempt to raise funds for Brain Tumour UK.

The RelayGB charity event in May will attempt to break the world record for distance relay running, covering 3,100 miles in 119 non-stop back to back marathons.

The challenge will pass through Truro, Helston and Tehidy on May 7 and 8.

The current world record, set in Romania in 2009, stands at 1,923 miles.

The route starts and finishes in London. Runners of all abilities can take part and at least two of the six runners on each 26-mile leg will need to be able to run a marathon in under four hours.

Runners can enter as individuals or as teams doing a 'relay within a relay' sharing the 26-mile leg. Corporate and running club entries are also welcome.

There is a £50 entry fee for individual runners and £80 for teams. Each runner will also be asked to raise a £1,000 minimum sponsorship.
