Fundraisers hope to raise cash by rowing the equivalent of more than 153km (95 miles).
The all-day joint venture between the Northamptonshire Disability Rowing Association, Oundle Town Rowing Club and Oundle School is at the latter on November 13.
Last year’s event raised £1,700 which NDRA put towards a grant from Sport England to buy a new Swift Quad.
The event is open to anyone but participants must be willing to raise or donate money to NDRA’s latest project – it hopes to buy a new rowing machine and organise on-water days for people with special needs. To take part email north- firstname.lastname@example.org or call 07411 322103.
