Now, I know £200 isn't much of an ambitious target - but great if you can help.

And I'd normally be doing lots of big, long swims.  This year, however, I've had a bit of a set back and not been able to do much.  My Lakes for Level Water swim on 30 August will be something of a tentative getting back in and reconnecting with the joy of distance swimming.

But who knows how far?  A free ZigZag Alive one to one session for whoever donates and comes closest to guessing what I'll end up doing.

Add your guess to the comment - or if you prefer to donate anonymously private message me.

Level Water want a world where everyone has access to swimming. For life. By donating to this challenge you are helping to make sure that, once pools have re-opened, lessons can continue straight away and children can continue to learn this life changing skill.
