They pedalled a total of 699km, the distance between the Normandy beaches and Arnhem, and all without leaving their junior ranks cookhouse.
The 24-hour challenge took place on a static Watt Bike, in the foyer of the Montgomery Dining Facility at the airborne medics' base, Merville Barracks in Colchester.
The organiser was Private Keith Ross who said:
"I came up with the idea basically to raise awareness of a good charity.
"I could have done it with a lot fewer people, but I thought let's get more people involved doing something that matters."
One of the team, keen cyclist Lance Corporal Matthew Hunter, said he got involved from the moment Pte Ross came up with the idea:
"ABF is actually fantastic and needs more promotion within the Army because you never know when you'll need to use it to help you and your family out."
Early one January morning, Second Lieutenant Owen Graham kicked off the event as the first pedaller, with the team reaching their goal at the same time the following day.
A trickle of personnel came and went through the night to check for aching muscles and stave off boredom.
As for Former Unit Welfare Officer Simon "Fez" Ferrier of ABF The Soldiers' Charity, he was there to see the starting and finishing stages of the 24-hour event and was keen to congratulate Pte Ross and the team.
"I'd like to say thank you to 16 Medical Regiment for volunteering to do this for ABF - which is the national charity of the British Army."
