TOUGH guys and gals can test their stamina by having a go at the Royal Marines Commando course for charity.
People from South Yorkshire are being invited to join the challenge, taking place next June.
Anyone aged over 16 is invited to enter and there is the opportunity to participate in four kilometre, 10 km and gruelling 17 km courses.
The event is on behalf of the Royal Marines Charitable Trust Fund as part of efforts to raise £6 million by October 2014.
Participants are asked to raise a minimum of £100 in sponsorship.
