I've raised £1000 to buy as many books as we can for the school library

As well as swimming, biking and running, I love to read. This last year has been a tough one for many children and at Burleigh Primary school, where I work, we try to make sure kids have access to as many different books as possible; but, there are still a few empty spots on our library shelves.
I will be completing the London Triathlon on the 8th August. I am doing the Olympic distance so this means I will be swimming 1.5K in the Royal Victoria Dock, then biking 40K into Westminster and running 10K near the Excel centre. I have never completed a longer distance triathlon before and I really want to have something to focus on when I am running that final 10K! Any contributions will be used to buy as wide a variety of interesting and mind-blowing books as possible so that children can lose themselves for a while in the world of their imaginations.
