Agbonlahor urging more entries for Saturday's Midnight Walk
"The event raised over £80,000 last year," Gabby said. "These funds are vital in enabling Acorns to provide support for life-limited children and their families.
"A good night's sleep can be hard to achieve for families with a life-limited child but by giving up just one night, the participants can make a real difference."
The 10km walk starts and finishes at Victoria Square in Birmingham on Saturday and takes in the cityscape's landmarks by moonlight, passing by the Bullring, the Jewellery Quarter, St Philip's Cathedral and Brindleyplace.
As the clock counts down to the deadline, Gabby is backing the Acorns team in urging more ladies to get involved.
Major events officer, Philippa Gay, said: "At the moment, the numbers are down, which is a cause for concern.
"The event will go ahead, but for it to be a success and raise as much as possible we need more women to sign up.
"If there are any ladies interested, I encourage them to get in touch; they will enjoy a magical experience with a wonderful camaraderie between everyone on the night."
Walkers must sign up prior to the entry deadline as entries cannot be made on the night itself.
Women can sign up with friends and family or individually (individual walkers will be introduced to each other on the night.)
The event is sponsored by First Personnel and a warm up and entertainment will be provided by the event's official media partner, Free Radio.
Midnight Walk entry is £12 and includes an event pack complete with fundraising ideas, training tips, sponsorship forms and a special Midnight Walk t-shirt to wear on the night.
Walkers also receive a medal in recognition of their achievement and support when they cross the finish line.
