PINK-clad ladies paced a loop around the borough during the early hours of Saturday morning while taking part in the women-only St Luke's Hospice's Midnight Walk.
The event was a sell-out and all the runners and walkers gathered at the start at Harrow Leisure Centre in Christchurch Avenue, Wealdstone, for a mass warm-up before the clock struck 12.
St Luke’s Hospice's director of fundraising Pam Russell said: "It was amazing to see so many individuals and groups from all sections of the community coming together to raise funds for our patients and their families.
"An outstanding £174 000 has been pledged so far.
"The walk wouldn’t be possible without the hundreds of volunteers who helped with all aspects of the event, planning, marketing, organising the breakfast, sponsorship and helping out on the night. "
The entertainment on the night included the all-female DJ pair Delicious Crew, dancers from Krupa Entertainment, who were captured on the video below, the Dhol Drummers, a fitness team from Everyone Active - which runs the leisure centre on Harrow Council's behalf - and local singer Lisa Lee.
Among those fundraising for the Kenton-based charity were worshippers from the new Shree Swaminarayan Mandir in Kingsbury Road, Kingsbury.
Pretal Varsani, from the temple, said: "Over 80 girls and ladies from the Mandir took part in the 9 mile walk, raising over £2000 and bringing the total raised to £26,000 and counting."
One group of friends walked together as Team Spirit. Member Jash Pindoriya said:
"Many of my friends and family are taking part today because it is a charity close to all of our hearts.
"In one form or another, the hospice is close to us and we want to give back to the community we live in.
"We have all experienced St Luke’s care and support and have all been touched by it.
"I am honoured and privileged to be here today. Our target was to raise £1000 but we have actually raised £2673."
The nine-mile route took in Harrow Weald, Stanmore, Kingsbury and Kenton.
