This run on a classic seafront promenade heads east of Brighton, mainly along the Undercliff Walk path. This route is along a concrete path, with great views of the English Channel, as you run underneath white cliffs. From Brighton Pier, the distance is up to 4.75 miles to the end of the path in Saltdean at the Telscombe Cliffs View. You can also include the 1 mile out and back jaunt along scenic Brighton Pier (can get crowded). Note that the beaches in the area are very pebbly and not good for running. Bonus: A bus runs along the main road, allowing for good one-way options! Our thanks to Kassie Helm for this route!
