Here are some messages of support that Radio 2 listeners have sent in for Sara so far this morning:

Sara paused to recognise the two minute silence for Remembrance Day.

Later, she spoke to Vernon Kay and reflected on the legacy of her late grandfather, who was posted in Italy during World War 2.

"We used to march every Remembrance Sunday and Grandad would be very proud with his medals on. Vincent Fulford. Quite the chap, he was. My Mum's Dad. He fought in Italy, he was an ambulance driver, caring for the injured and the dying, many of his pals amongst them. Just trying to get people to safety."

Sara continued: "It's always an important day for me. We stopped on a beautiful bit of moorland to observe the silence and look out at the skies and the treetops in the distance... We have a lot to be grateful for."

"It's really important to mark it... it puts it into perspective. It's only a bit of rain, eh? What's a bit of rain!"

Damon Albarn
Musician and Blur frontman

Last night, during Jo Whiley's Radio 2 show, Blur and Gorillaz musician Damon Albarn had this message for Sara...

Hi Sara, it’s Damon. I hear you’re doing something amazing for Children in Need. I can’t imagine doing a marathon every day! Good luck, hope you’re feet don’t get too sore. Lots of love.

This was just one of many moments where Sara found herself greeted by amazing supporters along her journey yesterday.

This is the kind of thing that keeps her going - so keep showing up for Sara, it means a lot to her!

To everyone messaging in to Radio 2, it's a real boost. Thank you so much.

And the donations? This total is ridiculous so far. Thank you so much to everyone who's chipped in a fiver, a tenner, even 20. Thank you, thank you.

When I spoke to Scott and he gave me the latest total, I was gazelle-like after that... for about eight seconds, and then I retrudged.

Sara is well underway now - you can track her movements here, external.

But if you're just joining us, here's the moment Sara set off from Hexham earlier this morning for Day 2!

I'm all over the place, if I'm honest. It's a real rollercoaster. I'll have two minutes where I'm like, "Come on, this is fine, let's do it," and I'm singing, "Oh, what a beautiful morning" as the icy rain splatters against my face. And then two minutes later, I'm like, "I can't do this. What's happening?"

So yeah, I am all over the shop, but, you know, we'll just keep ploughing on. Everybody donating just makes a massive difference and puts a spring in my step.

Sara's destination today is one of the first market towns in County Durham, known for its scenic routes through forests, moorlands and along the banks of the River Wear.

From the Victorian era to 1984, it was home to a major ironworks, and continues to host the Wolsingham Agricultural Society annual show, a tradition that dates back to 1763.

It's served by the heritage Weardale Railway, an independently owned British single track branch line.

You can follow Sara's every move with our very handy tracker, which charts her progress getting Pudsey to Pudsey - available now on the BBC Children in Need website, external.

Today, she kicked off her route from Hexham, after arriving there triumphantly last night, and is along the way to today's destination, Wolsingham!

I've got to confess. For the last little stretch, I've put on a little bit of Stormzy and Chase and Status - 'Backbone' - and I've powered along for the last 200 yards. That was my training song.

As mentioned, a special Pudsey backpack will accompany Sara throughout the next few days, as she aims to deliver him to the town in West Yorkshire that shares his name.

Sara will be carrying the Pudsey backpack, that was specially made for this challenge. It can be worn on her back or on her front.

Sara has said that before starting her challenge, she had a practice in her local park, running around with the Pudsey backpack, joking that she "looked like a weirdo... but he's lovely".

Pudsey has her back the whole way through! At least he's very lightweight...

As you may have seen, Sara has been accompanied by a very special guest on her trek so far.. the iconic Children in Need mascot, Pudsey!

Well, a specially-made Pudsey backpack, at least.

And as the rain starts to pour down on Day 2, even Pudsey has been trying to keep dry - thanks to this great waterproof Pudsey raincoat...

Anna Hindmarsh from the Whitley Chapel Young Farmer's Association spoke to Vernon Kay this morning from the Travellers Rest pub in Slaley.

She told Vernon how they had raised £400 with a charity bonfire in aid of Children In Need.

Sara Cox, I am in awe. You are incredible, this is the challenge of a lifetime. I cannot believe you are doing back-to back-marathons, from Kielder Forest to Pudsey for Children in Need. An incredible cause ,you are going to raise so much money, it’s going to be off the charts.

The chaffing? Let's keep that to a minimum! Let’s keep the spirit and the positivity right up here, because the whole nation is behind you.

I'm going to be thinking of you every step of the way. I might even run a 5k a day while you're doing it, just to be with you in spirit. Best of luck and see you at the other side!

It's grim right now. It's really grim and it's hard because it's uphill. It goes down and then up hill again, and it's so hard just to get warm and get all the blood flowing to the bits that need it.

I'm just like the Tin Man. Because as soon as I stop, everything tenses up again. The rain is driving down, the wind is icy. You just can't quite get going, it's just hill after hill.

It's just hard today to get a rhythm.

During his show this morning, Scott Mills spoke to Sara as she was about to embark on the second day of her Great Northern Marathon Challenge.

Reflecting on day one, Scott said that Sara "was putting a brave face on it" but felt "really rough when she crossed the finish line."

To help her through, Scott was rallying the support from across the nation, as listeners young and old called in to wish her good luck for the hilliest day.
