Pomorie is a lovely seaside town on a rocky peninsula that lies between Burgas and Nessebar. There’s some nice running in Pomorie, in two sections: a path atop a sandbar and a promenade alongside Secret Beach.

Sandbar Run. Google Street View

Sandbar Run: Just north of Central Beach, a sandbar extends for 6 km north to the Pomorie Saltpans. Starting near the Grand Hotel, the first 1 km is on a paved road where there are parked cars. Then the road ends, and a dirt path continues north along the sandbar for another ~5 km, ending at the Saltpans. It’s open and exposed, with good views, and a bit monotonous. Notes: It’s possible that the sandbar is flooded or submerged at times. Please consult locals and tide times. Note: There’s work to improve the path along Central Beach, in the main part of Pomorie.

Beach Promenade. It’s possible to run for nearly 4 km along the water from the Pomorie Center Science Museum west to the Helios Hotel. The first km includes a jaunt out to the Old Port and then on beach-side sidewalk along the main road. Then, just past Pomorie Pier/Pomorie Sign, a paved dedicated path runs west along Secret Beach for another 3 km.  There are good sea views the whole way. Note: the beach is also runnable.
