A bunch of Lippert Marine team member landlubbers (okay, a couple of us are sailors!) are going to scamper up and down the highest peaks in Scotland, England and Wales - all in a day! This will involve walking about 37km (23 miles) - call it Havant to Winchester, or Catfield to Sheringham - with a vertical climb of 3064m (10,052ft) - that's 700 storeys of a building.

The drive between the three peaks is 462 miles - that's before we even arrive at the first and drive home from the last.

For all this, we are keen to raise as much money as possible for Water Aid. Lewmar / Trend Marine have kindly agreed to chip in but most of what we need to raise will come from those we know. This is where you can help.

WaterAid is an international not-for-profit, determined to make clean water, decent toilets and good hygiene normal for everyone, everywhere within a generation. Only by tackling these three essentials in ways that last can people change their lives for good.

Clean water, decent toilets and good hygiene should be a normal part of everyone’s daily life. Without all three, people can’t live dignified, healthy lives. With all three, they can unlock their potential, break free from poverty and change their lives for good.
