Wow! You certainly spent a lot of time putting this together. Thanks. Can't wait to use it when I get the right class.

Thanks for sharing this excellent resource - an interesting and challenging 'real-life maths' activity.

Fantastic! Answers that old question about when are we ever going to use this. Really interesting. Thanks

You might want to save this for the next Olympics, or indeed the Commonwealth Games, but, either way, this is a fabulously produced presentation with accompanying worksheet. It's perfect for allowing able students to apply their knowledge of indices and substitution. You could even extend the task to get students to produce graphics of the heptathlon leaders event by event. Thanks so much for sharing this resource that, evidently, took a great deal of effort to produce.
