About 1,000 walkers are expected to take a stroll in the park on Saturday for St Luke’s Hospice Starlight Walk.
The annual 5k walk from Endcliffe Park to Forge Dam begins at 9pm, with entertainment starting from 6.30pm.
More than 800 people have signed up for the event, and organisers anticipate a late surge in entries.
“It’s very emotional and very uplifting,” said a spokesperson. “A lot of people taking part because they have personal experience of why the hospice needs support.”
Joining the event again are Nick’s Night Strollers, aiming to raise at least £1,000 in memory of 49-year-old Nick Milton, of Crookes, who died at St Luke’s last year.
“We really enjoyed it last year and there was a really fantastic atmosphere so we wanted to do it again,” said Nick’s daughter, Gemma Milton.
“At first we thought it might be a bit sad, but when you see all those people walking in memory of people they have loved, it feels really good and it’s very positive.”
Registration of £15 for adults and £10 for children covers the cost of staging the walk, with walkers urged to seek sponsorship.
The date has switched from May, partly because it would have been on the eve of the Sheffield half marathon.
