WLZ work with schools, nurseries and children’s centres to support children and young people with a range of development opportunities provided by their strategic partners.

Every December teams of brave rowers take to the Atlantic Ocean at La Gomera, Canary Islands to tackle to winds, storms and challenges and reach Antigua.
The race spans 3,000 miles, and teams spend over one month at sea, with little rest and not much space to relax in their small boat when they do down their oars for the day.
A gruelling challenge, deemed the world's toughest row, the race is not the light-hearted and requires strong stamina, a clear mindset and a lot of determination.
