Cyclists from Garstang Community Academy are aiming to become the first group of students to complete the coast-to-coast Trans Pennine Trail.
The students will set off at 9am tomorrow in a bid to conquer the 220 miles of track from Southport, Lancashire to Hornsea, Yorkshire, overlooking the North Sea.
They will be raising money for Help4Heroes and North West Air Ambulance, and have set themselves an ambitious target of £3,000.
The youngsters will spend their first night in Liverpool and the second in a youth hostel at Crowden before they reach the top of the Pennines.
They will rest on the third night at a Premier Inn in Goole before riding the final 50 miles through Hull to Hornsea.
Simon Millward-Hopkins, ride organiser and head of history at the school, said: “I don’t think we have had a more enthusiastic and keen group of riders in the many years the school has been completing charity challenges.
“They have trained hard, starting in the cold wind and weather of January and March, have passed BikeAbility training at level two, and are more than ready and prepared to face the rigors of 60 miles plus in the saddle.
“I think I am as excited as they are by the prospect.
“What a wonderful way to end a long and busy year.”
Sponsors include FarmHouse Biscuits, which provided six boxes of goodies to keep the cyclists full of energy, SJ Bargh transport, which have provided a large lorry to bring the luggage and bikes back home, Bristol Oilskin and Overall Company, which has made hoodies for all the riders, and Edinburgh Bikes, which has supplied nutritional bars and drinks.
