Michael Sobell Hospice staff are looking forward to the "biggest" ever Ladies in the Night Walk.
Staff were pleased to announce that 1,000 people have signed up to take part this Friday (June 12).
Sponsored by Savills estate agents, it is the biggest event in the hospice’s fundraising calendar and has been running for five years.
Martinne Aston, a member of the Gymophobics Team in Ruislip Manor, became the 1,000th person to sign up to the event.
Ophelia Chambers-Henry, events & community fundraising manager, said: “This year’s event is going to be the biggest one yet, there will be a great party atmosphere and community spirit and we really hope to smash our fundraising target.”
The hospice is hoping to beat its fundraising target of £80,000.
Last year's event saw 400 people raise £60,000 for the hospice, which looks after local people with life-limiting illnesses.
Walkers can choose from either a 5½ or 9-mile route, which starts and ends at the hospice in Northwood.
The event will start with a fun Zumba warm-up session on the lawn followed by a magical moonlit walk with live entertainment along the route through the local area, before returning to the hospice for a well-deserved breakfast.
Men, women and pooches are encouraged to dress up in pink with flashing headgear and accessories.
Many of the participants are walking in memory of loved ones, have a close connection to the hospice or simply just want to support a great local cause.
