Nobody has reviewed this one yet

No reviews of the CTS Suffolk, 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

Dunwich, and by Endurancelife's own description extremely flat by their standards — the 32-mile ultra has 1,129 ft of climb, which is less than the Exmoor 10K. Forest, moorland, grass and beach through a quiet stretch of the Suffolk coast. If you want to know what you can actually run over an ultra distance without the ground taking it out of you, this is the one in the series that tells you. Fully marked, no navigation.
