Coverack to Porthtowan, Cornwall
The one everybody has heard of, and the reason a lot of people find the Cornish coast path in the first place. The 100-miler goes point to point from Coverack round to Porthtowan — 173km and 5,507m of climbing, most of it in the dark, in January. Shorter races follow over the weekend: 100K on the Saturday, then 50K and 20K on the Sunday. It has run since 2015 and grown from fifty starters to one of the biggest trail events in the country.
