If you’re just joining our live coverage of Sara Cox’s Great Northern Marathon Challenge for BBC Children in Need, here’s what’s been going on…

• Radio 2’s Sara Cox is feeling the pain on Day 3 of her challenge - and has even had to resort to walking backwards.
• But she's been spurred on by your generosity, with over £1million raised so far.

• Throughout this week, Sara’s mission is to cover 135 miles on foot carrying a special Pudsey Bear backpack to Pudsey in West Yorkshire, powered by northern grit and a whole lot of listener love.
• She's just arrived in the village of Hamsterley in County Durham, aiming to reach the town of Richmond in North Yorkshire by this evening.

Stay tuned for regular updates, photos and videos as Sara continues her epic journey!

My message is not so much for Sara, it's for everyone else - people power.

When I did my challenge, that's what got me through, and you won't realise it, you might be looking on the live tracker and you know Sara's coming through your town and you might think "she'll be alright" - get out.

Get out, support her, it's so important. Whether you donate or not, get out, get on the road, cheer her on.

People power - that's what got me over the line.

She's right in the eye-of-the-storm now, she's got through the exciting of the first day, and then it slowly dawns on you, when you're on the the roads on your own, it's quiet, it's cold, it's raining.

You feel a bit dejected, but you see someone on the side of the road, they smile and it carries you through.

It's been an emotional morning, with Sara facing the "hump day" of all hump days on Day 3 of her Great Northern Marathon Challenge after a sleepless night.

Scott has delivered messages of support throughout the show, from fellow presenters, a Northern legend and from the amazing Radio 2 listeners.

Catch up with everything that's happened on Day 3 below...

• Emotional start for Sara
• We hit over £1million!
• Radio 2 team join Five for a special mash up
• Peter Kay delivers a message of support

Northern legend Peter Kay had a special message for Sara earlier...

Hello Sara, it’s Peter. This, what you’re doing now is a massive challenge - huge! I thought Paddy and Vernon had it hard, but you’re taking it to the next level! What’s next, Scott Mills skipping up the M1?

Your poor feet! Listen, whenever you’re up against it, when you feel like you can’t go on, and the tops of your legs are chaffing, just think of Children in Need and what it means.

Saying that, all that money they’ve raised and they’ve still not fixed Pudsey’s eye!

When Sara found out that she had raised over £1 million for Children in Need!

Don’t be nice to me, because you know I’ll be doing some ugly-crying by the side of the road. They promised me undulating today, that was a lie! This ain’t undulating - it’s mountainous!

I’ve got the laughy-cries, I heard Peter Kay’s message which was amazing, Jo Whiley taking part in a Five song just gave me a real boost, it can't have come naturally, so thank you Jo.

Sara Cox is well on her way for Day 3 of her Great Northern Marathon Challenge.

The ascent was gruelling yesterday, and the hills don't stop there I'm afraid. Today, I've looked and it's hill after hill. If you've ever done something incredible, like a half marathon or marathon, and you've trained so hard for months and you get those miles done, and everyone's cheering around you and you feel so proud of yourself, what an accomplishment.

Imagine that feeling, but then, you wake up the next day and you've got to do another one.

This is ridiculously tough, she's doing this all for Children in Need - your donations will make such a difference.

If anything could lift Sara's spirits today then it was always going to be the amazing and generous donations from the Radio 2 listeners!

And Scott Mills just revealed on air that the latest total is in... and we're over the million mark!

The official latest total is... £1,002,869!

That is incredible support for Sara, for Children in Need and for the Great Northern Marathon Challenge!

We can't thank you enough! Find out how to support Sara with a donation.

Watch this video of Sara setting off from Wolsingham for Day 3 of her challenge - the hilliest day!

We're all rooting for you, Sara!

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

As Scott Mills just noted on Radio 2, Sara is now trying to walk the next stretch backwards - because she's in a lot of pain.

"If I'm honest, she's really, really struggling this morning," Scott said. "I really feel for her. She needs all the help she can get."

Radio 2 have just premiered a brand new mashup of the 1999 hit single Keep On Movin' by the group Five - with extra vocals from the Radio 2 family.

Formed in 1997, Five were one of the most successful hit Brit boybands and sold over 20 million records. With smash hits like Keep On Movin', If Ya Gettin' Down and Everybody Get Up, it's no surprise they were such a global success.

At the height of their popularity all members called it a day due to stress and pressure, with Abz claiming in a BBC interview that the rise to fame was "too much too fast - way too fast."

25 years after their split, Abz, Jason, Ritchie, Scott and Sean are reuniting for the Keep On Movin' arena tour - much to millenials' delight.

The reunion didn't come without its worries, with the band unsure they could still sing and dance! However, rehearsals have confirmed that all members have still Got The Feelin'.

With Sara facing the hilliest day of her challenge, let's hope this fresh take on one of their signature tracks proves just the motivation she needs to get across those hills!

Scott Mills just aired a great mash-up from Five, featuring extra vocals from the Radio 2 family! Recorded especially to help Sara on along the way!

Let's hope this gives Sara the boost she needs for Day 3!

Scott and Richie from Five were on Radio 2 to send support to Sara:

"Sara has always been a big supporter of us, we’re very close with her. We’ve got nothing but words of encouragement for her, but we thought we’d go one step further, so we just rewrote Keep On Movin’ for you!"

A weary and under-slept Sara took comfort in a warm greeting from the crowds, who gathered at Wolsingham to send her on her way for Day 3 of her challenge.

Sara's Great Northern Marathon Challenge for BBC Children in Need is well underway!
