Over the past 18 years, sponsored riders have raised nearly £1.2M for Les Bourgs.
This year is the 35th anniversary of the founding of Les Bourgs Hospice.
Unlike other hospices in the UK and Jersey, it currently receives no government funding, which is where the 30 Rides idea comes in.
Cyclists of all ages and abilities sign up to commit to at least one hour per day on the bike in May.
Ideally, each rider or team has £900 or more of sponsorship money backing their effort.
Over 18 years, 642 riders have raised a stunning £1.17M for Les Bourgs.
50 are signed up this year already and will wear trademark jerseys to mark them out on the road. This year the colours are lilac and green.
Well known island and Commonwealth Games cyclist Ian Brown is the organiser of 30 Rides in 30 Days.
The Hospice CEO, Rob Jones, says the fundraiser is essential to them:
“30 Rides in 30 Days is one of those events that truly embodies the spirit of Guernsey.
"It brings people together, challenges them personally, and delivers an extraordinary impact for our charity.
"The funds raised continue to make a real difference to the care we provide to islanders and their families. As we celebrate 35 years of Les Bourgs."
30 Rides ends with the Rocque to Rock mass ride on 31 May.
