Why we need you
Great Ormond Street Hospital Charity needs your support more than ever. Your registration fee goes towards the cost of putting on the Tower Climb event, so by fundraising, you'll help to fund:
- groundbreaking research
- advanced equipment
- children and family support services
- the rebuilding and refurbishment of wards and medical facilities within the hospital.
What happens on the day
The time you selected during the registration process is your arrival time. The first arrival time is 8am, with the climb starting 30 minutes later. There are slots every 30 minutes to choose from.
There are 36 floors to take you up to the Sky Garden which adds up to an impressive 896 steps!
You can run, jog or walk your way to the Sky Garden - whatever you feel most comfortable doing.
Your friends and family are more than welcome to wait in the Sky Garden to see you cross the Tower Climb finishing line.
Everyone is welcome to stay in the Sky Garden after their Tower Climb challenge to enjoy the stunning views.
Help with fundraising
Everyone taking part in Tower Climb are asked to fundraise a minimum of £250 in sponsorship. This goes towards all the amazing, lifesaving work that Great Ormond Street Hospital does.
It's quick and simple to create a JustGiving page to kick start your fundraising. Get in touch with the Tower Climb team if you would like any fundraising materials or need any advice.
You do not have to have reached the full fundraising target by the date of the event.
