FIT and keen walkers are being signed up for an overnight endurance challenge.
Children's charity Action Medical Research wants people to join the Cotswold PLOD on June 7.
It is a tough all-night trek, setting out from Dursley.
Teams will need to walk through the night, navigating a 40-mile route along the Cotswold Way using head torches.
As day breaks, they will be rewarded with breathtaking views and stunning scenery.
Participants will also need to use teamwork, strategy and intelligence to gain bonus points for completing additional challenges along the way.
To take part in the Cotswold PLOD, you will need a team of four walkers and a support driver, plus vehicle. Anyone interested can register for one of the places at www.plod.org.uk/cotswold.
