No reviews of the Gatliff Marathon, 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
The forty-second Gatliff: 50km or 25km on footpaths and tracks through the Kent, Surrey and Sussex Weald from Edenbridge cricket club, a new route every year, ten hours, five checkpoints and a GPX to download beforehand. Mid-October.
Terrain and trail
The Weald: clay field path, woodland and green lane, famous for mud — the organiser tags it that way themselves. Rolling rather than hilly. Self-navigated. A trail shoe with grip.
