"RotarySwimarathon" is organised by the Rotary Club of Grantham to support local charities, organisations and deserving causes/projects in and around Grantham. In the first 36 years over £1million has been raised and in 2025 an all time record of £55,000 was raised.

Ruskin hopes to have as many students as possible take part and raise sponsorship funds for this fantastic local charity event.
