Why fundraise for Rainbows?
We can’t do the work we do without your support, so in addition to everything provided by Ultra Challenge, Rainbows will provide:
- A dedicated member of the fundraising team to support you
- A Supporting Rainbows technical t-shirt when you raise £100
- A fundraising guide, as well as fundraising advice, hints and tips in the build up to the event
- Access to a range of Rainbows fundraising materials (collection boxes, posters, balloons etc.) to make any events you hold look amazing
By fundraising for Rainbows you will be helping to support babies, children, young people and their families living with life-threatening and life-limiting conditions, here in the East Midlands.
We support every baby, child and young person to fulfil their potential, and help families make the most of every precious moment, while capturing memories and keepsakes to treasure. We’re here for the whole family, offering comfort and compassion during tough times, providing the highest level of professional care until the end, and support after. Simply put, we’re here to brighten short lives, and support families, wherever they are.
Every penny you raise, will help support our vital work here at the Hospice, in the local community and in hospitals.
