Leicester Tigers women's Strength & Conditioning lead Lewis Knight will be undertaking a mammoth challenge in aid of the MyName5Doddie foundation.
Knight, alongside friend Craig Thompson, will be beginning their challenge in Scotland, by climbing to the top of the UK's highest peak Ben Nevis.
Over the following two days, they will then be cycling south, across Scotland and down through the north of England till they reach the Lake District.
Here they start the second part of their 'three peaks', scaling Scafell Pike.
Finally, they move South-West, crossing borders again, this time into Wales and, on Saturday August 12, they begin their final ascent and tackle Mount Snowden.
The pair are raising money for MyName5Doddie foundation and if you would like to support, you can do so via the link below:
