South Coast Run routes

The run is a simple out and back course along the esplanade at Seaford which is flat and fast.

The vast majority of the course is on good level tarmac.

A very small part of the course near to the finish line is gravel and then grass.

Please take care on the run course as there may be pedestrians.

When you have completed the required lap(s) filter into the finish alley on Martello Field and through to the finish line (signed and clearly visible).

There is a feed station on the run course at approximately every 1.5 miles and at the finish line serving High5 sports drink and water.

    What is the cut off date for entries to the half marathon


    Steph E
    Hi there, we are taking entries up until the 1st of August (unless it's sold out by then) - but we would advise booking sooner rather than later to avoid disappointment though! Thanks

    Is the half marathon route laps along the seafront or does it go inland?


    Steph E
    Hey there, just to let you know that the course is a up and back course along the the coast line. It follows the beach front for 1O kilometres before turning around and heading back to the finish. The only part were it goes inland is the finish area however the sea is visible the entire time. Best of luck!

    Did the Half Marathon in 2019

    Very nice scenery, nice atmosphere, easy access. Very friendly and Professional staff. Small crowd , but very enthusiastic.
  • Did the 10K in 2019

    A great run, I decided to cut down to the 10km as training had changed. I think for 5km and 10km it’s a perfect course. I don’t know if doing four Laps would get a bit repetitive but dead flat so all good!

    Only complaint.... not enough toilets ! Only 7 available. Told there were toilets on the promenade but they were closed anyway 🤷‍♂️
  • Did the 10K in 2019

    First entered organised run, will be back next year really enjoyed it, may even do the half marathon.
  • Did the 5K Fun Run in 2018

    This was my first ever race! And boy, I don't think the weather got the message, but if anything it made my race what it was, a sub 40" 5K in sideways rain!!! loved it
