We're back after a short break. In this episode, Sarah talks about the increasing media and speaking demands being made of her. Not a natural publicity seeker, she has taken on a publicist to help her promote the Great British Viking Quest and raise her profile. She speaks honestly about the issues of self-image relating to increased celebrity and the pressures it is putting on her.

The research that Sarah will be doing during her row has brought her in contact with NASA. There is news about her charitable status. Most significantly, the change in date of this year's Technopop has had a big impact on her plans and the row itself.

This week Sarah is joined by Clare Jefferies of She Marketing. We discuss how Clare is helping Sarah promote her cause and the benefits and drawbacks of being a female rower when dealing with the press. We also have HUGE news...

Sarah has been accepted on to a PhD programme and will be studying the cognitive effects of calorific stress on rowers. She will be her own first test subject during the Great British Viking Row. She talks us through the research and the delicate issue of faeces – one of the study's key data sources. For instance, just how do you explain a box of it on your way through airport customs?

This week, Sarah is joined by Jo Tall – her legal counsel. We find out just how much legal advice an ocean rower needs. Turns out, it's quite a bit. For instance, it's illegal to swim with the fishes sometimes. This is also crunch time for Sarah as she races to raise the first instalment for her boat.

This week, Sarah joins us from the British Museum in London and talks about Vikings. We compare their boats and nautical lifestyle with hers. We talk food, technology and seasickness. She also reveals that her body has endured a lot already in life, including paralysis.

Sarah has decided to take on an even more daunting row – one that hasn't been done before: around Britain. Listen to find out more and find out about Pink Martini, who have donated the podcast music.

The Oceans Project Pacific Ocean row has been hit by a bit snag. In this episode, Sarah explains what has happened. We're also joined by Peter May of the Bisham Abbey Sailing and Navigation School in the UK, where Sarah has been undergoing sea survival training.

While they row across the Pacific Ocean, Sarah and Susannah will be collecting water samples to help with research into #microplastic #pollution. In this episode, Susannah explains exactly what the problem is.

In this episode, Oceans Project skipper Sarah Weldon talks about her recent audition to become the face of @YorkshireTea Gold. We do a quick calculation of the number of cups of tea that will be consumed on the voyage. Sarah talks about the pressures that come with undertaking such a role and her thoughts on how she will feel once she's completed the journey.
