To atone for the lifetime's guilt of allegedly putting my foot down during my 25m test in Newtownards Baths in 1978, I have decided to take on a 10km swim on 21st September up the Afon Mawddach estuary into Eryri (Snowdonia). If we're quick enough, we will have the benefit of the incoming tidal bore, so it will definitely be a different sort of Saturday morning.

The event is also being run to generate funds for the charity Level Water, helping to improve lives for children with disabilities by giving them the opportunity to also enjoy the water. I am conscious of testing your generosity once again but if you were able to spare some change that would be hugely appreciated.

Thank you very much.
