The 2.6 Challenge We’re taking part in the Virgin Money Giving 2.6 Challenge! A team of intrepid Marks Hall Estate staff will be donning their trainers and taking it in (socially distanced) turns to walk, skip, jog or even run 26 kilometres around the Arboretum over the next week. Managed and cared for by a charitable trust, the valued support you give plays a really important role in the conservation and education work that we do on the Estate. As a registered charity, the Trust is dependent on its own resources, and with your assistance we will ensure that this special place can be enjoyed by generations to come. Throughout the week you can keep up to date with the team's journeys on our social media pages - Facebook, Twitter, Instagram and YouTube. Meet the team and donate now on our Virgin Money Giving page.
