Staff at Birchwood Medical Practice in North Walsham are doing a cycle-a-thon to raise money for a community defibrillator.
The team is aiming to raise £2,250 for the lifesaving equipment, which would be located at the front of the Park Lane practice with 24-hour public access.
District and county councillor Lucy Shires, who is supporting the fundraiser, which runs 8am-6pm today (Tuesday), said: "When someone has a cardiac arrest, every second counts.
"Together with CPR, the prompt use of a defibrillator is critical in giving people in our community the best chance of survival.
"In the North Walsham West there is only one other 24-hour publicly accessible defibrillator which is at Waitrose.
"A more accessible defibrillator could be the difference between life and death."
All of those taking part in the cycle - on two static bikes at the practice - is in the saddle for 30 minutes.
