Oi Slaaaaag, try Bletchley Leisure Centre for pool swimming. I am not sure about OW venue but why not PM Barlos as I know he would have some ideas
I was googling one day and it seems there is a lido near MK . I will see if I can find it
Hahahaha! Cross post
It's worth having a look here - http://wildswim.com/ to see if there's anything useful to you. It really depends where in Milton Keynes you'll be and how far you're willing to travel
Avoid the A5! I've driven on it countless time and would never recommend cycling on it - far too fast and busy.

Give me a shout if youre around MK, happy to meet up for a bike ride.
