Cambridgeshire police officer, Rob Tindall, pedalled 435 miles and ascended 16,900 feet, raising £825 for charity.
Tindall completed his Lap of Anglia Charity ride last week with proceeds going to the East Anglian Air Ambulance Charity, which provides around-the-clock critical care by air and road.
A spokesperson for Cambridgeshire Constabulary said: "Thank you to everyone for all the support and donations."
They added, "Well done Rob, what a great ride!"
