Get involved Join an event Ballot places and bespoke challenges Ballot Places Have you entered the ballot for London Marathon 2019 or another challenge event? We would love to hear from you! Join #TeamGlassDoor and raise funds to bring shelter and hope to those who need it most. As a ballot runner, there is no minimum sponsorship. We would work with you to set an appropriate fundraising target and support you all the way. We can provide running and cycling jerseys to let everyone know of your support. Bespoke Challenges Alternatively, get in touch about creating a bespoke event. We can work with you to select any number of events run by third party companies like Discover Adventure, who are experts in trek and cycling challenge events in the UK and countries across the world. In the past, a team of Glass Door supporters have cycled to Paris through their programme.
