A Chap called Newton Mystery Cache

At 2am on 8th January 1928 at this point outside of the "Bear" public house in Box, now the "Bengal Bear" Ultra Distance runner Arthur Newton lined up to run the 100-miles to London. In doing so he set a new world best for the distance of 14-hours 22-minutes 10-seconds when he crossed the finishing line in Hyde Park. Then following this run he did something quite unforgivable in the eyes of 1920's athletics - he became a professional athlete!!!

So I am inviting you to uncover some of Arthur Newtons achievements which will lead you to the cache location...
