Jonathan Hanna, who is in our S6,  is to cycle coast to coast across America in just 30 days.  He hopes to cover an average of 100 miles a day.

He will be joined on his gruelling 2900-mile challenge by dad Gavin.

They will be cycling every day, with just two emergency days in reserve in case of breakdown.

And there is no support crew following behind – Jonathan and Gavin will be carrying all their gear themselves on the bikes.

This includes camping equipment, as they are planning to camp out as much as possible.

They will be raising money for Scottish charity the Vine Trust, which is currently equipping a medical ship to send to Africa.

The epic USA trek starts in Los Angeles before heading through southern California and into Arizona where Jonathan and Gavin will make a 35-mile detour to cycle alongside the Grand Canyon.

Next they’ll cross the desert to Colorado where they will cycle over the Rockies, scaling the highest point in their journey at 10,857ft.

Then it’s down into Kansas and through Tornado Alley before crossing another seven states, including Washington DC. End of the very long road will be Annapolis in Maryland.

Jonathan and his dad have a fundraising target of £5000 and have already raised £2000.

The Vine Trust is equipping its latest medical ship in Greenock, from where it will be sent to Lake Victoria in Tanzania to deliver medical and dental aid to isolated communities.
