Equipment supplier Concept 2 and charity Help for Heroes have joined forces in a campaign to encourage people to get on rowing machines and raise money for members of the armed forces who have been wounded in service.

There are a number of challenges outlined on Concept2's website and there's also a section where you can log your distances and money raised.

The finale will take place on 21 November at the British Indoor Rowing Championships. Details: www.concept2.co.uk
