Jackie, Liz and Chris are cycling the 961 miles from Lands End to John O’Groats over 13 days in September.

We’ve planned the route ourselves to avoid the worst of the traffic and will be staying at a combination of B&Bs, youth hostels and friends’ houses along the way.

For support, our parents have kindly agreed to take it in turns to follow us up the country, laden with energy bars, flapjacks and a list of bike repair shops.

As an added incentive as we tackle the undulating terrain Britain throws at us, we’re raising money for charity.

It promises to be a tough challenge and a great adventure.
