This September, two Whales will do what no two Whales have ever done before.
They will don extremely well-fitted wetsuits and swim 10 kilometres along the Dart River from Totnes to Dittisham. That's the equivalent of swimming 400 lengths of a standard pool, without stopping.
Now, you may be thinking this is just for fun... Most likely you think we're mad! (We are a little bit.)
But, it's all in aid of a pretty darn wonderful charity, the Glenn McMahon Foundation for Brain Tumour Research.
If you're still wondering why you should donate to Brain Tumour Research, you might be shocked to find out that brain tumours kill more children and adults under the age of 40 than any other types of cancer. Yet, they receive just 1% of the national spend on cancer research.
Glenn McMahon was a pretty awesome guy, a close friend of Spud and the Whale family. But more importantly, a much-loved husband, father, step-father and an excellent golf player. However, in 2013, he was diagnosed with an aggressive brain tumour and sadly passed away in June 2015 at the age of just 53.
Since his passing, his amazing wife Wendy has been working tirelessly to raise money to help increase awareness of this type of cancer, as well as supporting the much-needed research surrounding this awful disease.
We would love to help Wendy on her mission and raise as much as possible for the charity. But, as with all fundraising, it's important to note that every little helps - it really does.
Whether you can donate £5 or £50, it all goes directly to the charity and it all has a positive impact on people's lives.
So thank you.
