Registration for the fourth annual Ruby Ride is open.
The bike ride, which raises money for The Rowans Hospice, will be held around Portsmouth, Purbrook and Petersfield on Sunday, September 20.
With a choice of three routes of 18, 30 or 65 miles, the event appeals to casual bike riders as well as the more competitive cyclist.
Participants are encouraged to raise money which goes toward providing hospice care in Portsmouth and south-east Hampshire.
The Ruby Ride has raised £160,000 over the last three years.
Karen Kay, events fundraiser at The Rowans, says: ‘The Ruby Ride is now an established event for cyclists of all abilities. Even if you haven’t been on a bicycle for years, come and take part.
‘All three routes start and finish at Lakeside, North Harbour. It’s not a race and there are refreshment stops en route for all cyclists. Everyone taking part receives a T-shirt to wear on the day and medal when they cross the finishing line.
‘We ask participants to raise £100, but every pound makes a difference.’
The hospice in Purbrook is hosting a launch event at 1pm today, accompanied by the Ruby Ride partners the Bicycle Recycling, Dirt2Road and Serv Bikers with cakes and refreshments provided courtesy of the Co-op in Denmead.
Online registration will be available at rowanshospice.co.uk after the official launch.
Registration forms will also be available from all of The Rowans Hospice charity shops.
