Starting on Friday, March 13, Greg James, 40, is cycling on a tandem bike from Weymouth, Dorset, to Edinburgh, Scotland, as part of an eight-day challenge.

As part of this 630-mile (1000km) journey, Greg will pass through parts of Somerset – all for Comic Relief.

With a full official route yet to be confirmed, a spokesperson for Comic Relief confirmed that Greg will be visible passing through Somerset on the first day of the bike challenge.

“I can confirm that Greg will be travelling through Somerset on his challenge,” said a spokesperson for Comic Relief. “He will be starting in Weymouth and finishing in Bristol on Day 1.”

The breakfast radio presenter will be riding mostly solo during each eight-hour daily leg, but says he will be joined by other Radio 1 presenters and some special guests along the way.

It’ll be Greg’s third Red Nose Day challenge after completing five triathlons in five days in 2016 before cycling between Scafell Pike, Snowdon, and Ben Nevis – climbing each of them – two years later.

Starting in Weymouth, he’ll then ride through England and Wales – passing through villages, towns and cities – before ending at the finish line in Edinburgh on Red Nose Day on Friday, March 20.

Less than a month until the challenge begins, Greg says he expects to be joined on the tandem by a “mixture of well-known people and [Radio 1] listeners”.

“I need them to be good cyclists,” he said.

“The reality of it might be that they wobble and we both fall off.”

Greg says he’s coming out of “challenge retirement”, but it’s going to be “brutally hard and relentlessly demanding”.

“The world feels really overwhelming at the moment. There’s a lot of things to worry about and everything is just feeling a lot,” he says.

“I’m dedicating this challenge to anyone who feels like they’re carrying life’s load on their own.”

Greg James’ cycle ride will be broadcast live across Radio 1, Morning Live and BBC Sounds during his journey.
