No reviews of the Autumn 100, and nothing on what people wore. Both are things no organiser publishes and every runner wants before they enter — how it actually went, and what was on your feet.

What you’re in for
Four separate twenty-five mile out-and-backs from Goring-on-Thames, run as a cross: down the Thames Path to Little Wittenham and back, out the Ridgeway to Swyncombe Farm and back, the Ridgeway again to Chain Hill, then the Thames Path to Reading. You pass through Goring four times, which is either a comfort or a torment depending on the hour. Four fifths trail, marked with national trail acorns plus Centurion ribbons and arrows. Sixteen aid stations and twenty-eight hours to finish.
