Nobody has reviewed this one yet

No reviews of the CTS Sussex, 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

Eastbourne and the Seven Sisters — the white chalk cliffs, and the rolling downland behind them, with the Channel out to one side the whole way. Chalk and forest, rated strenuous: the marathon carries 4,196 ft and the ultra 5,266 ft, which for the South Downs is a lot, and it comes in the repeated drops and climbs over the Sisters. Fully marked, no navigation.
