People will be cycling, walking, riding horses and driving tractors as they visit over 8,000 churches, chapels and meeting houses on Saturday.
The sponsored event aims to raise funds to make repairs to Christian buildings.
Eddie Tulasiewicz from the National Churches Trust told Premier that people are using all sorts of transport.
He said: "People go on very long cycle rides, particularly in flat parts of the country, or they go walking in cities, and there's all sorts of other transport - there's tractors, there's prams, even people who're use a mobility scooters, or people just drive from one church to another."
He said: "I'm going to be walking around the city of London with umbrella in hand because I understand it's going to be quite wet.
"The good thing is in the city of London you can go from one church to another fairly quickly, so we're you're in the church it's fairly dry - so fingers crossed it won't rain all day!"
People are sponsored to visit as many churches as they can in a day and aim to raise £1.5 million to help pay for urgent repairs to buildings.
Eddie Tulasiewicz went on: "People get together and do something to save their historic churches, it's a real coming together of parishes, people who know one another, people who just come along for the day, to donate to charity to look after England's historic churches."
Currently, there are 887 churches on Historic England's 'Heritage At Risk Register' and urgently need external funding support to deal with repairs to roofs, stonework, spires and towers.
