Coppa Byron

In the height of August, the water temperature in the Gulf of Poets typically hovers between 24°C and 26°C, offering a comfortable environment for the long-distance effort required by the 43rd Coppa Byron. Swimmers should anticipate variable surface conditions; while the morning often brings calm, the interaction between the open sea and the enclosed geography of the gulf can generate mild chop as the day progresses. The event, now in its 43rd edition, is a point-to-point race that historically connects the village of Portovenere to Lerici, tracing a route that demands navigation alongside the historic maritime defenses of the region.

Historical currents of the Gulf

As you navigate the stretch between the two headlands, you swim through waters that have served as a natural theater for military and literary history for centuries. The Castello di Lerici, looming over your arrival point, was a core strategic asset during the medieval power struggles between Genoa and Pisa, and it famously provided shelter to the admiral Andrea Doria in 1528 as he plotted the liberation of his city. The coastline is equally marked by deep time; in 1987, researchers identified fossilized dinosaur tracks within the Lerici alluvial plains, evidence of a coastal landscape dating back to the Late Triassic period, nearly 220 million years ago. This area is recognized as the 'Golfo dei Poeti'—a name solidified by playwright Sem Benelli in 1910—to honor the presence of figures like Lord Byron and Mary Shelley, who lived and wrote within these specific coastal boundaries.

Race day logistics

With the next edition scheduled for August 9, 2026, the organization manages the complexities of a maritime transit through a dedicated logistics protocol, which is reflected in the registration fee. The entry includes a timing chip and a race pack, and the fee supports the necessary coordination of water safety, including escort vessels and the regulation of local maritime traffic to ensure a clear lane for participants. For those looking to manage their calendar, the Palmaria Island Swim takes place earlier in the season, while the Miglio Marino di Punta Bianca provides a different pacing in late August. As you approach the finish line, look toward the promontories of Fezzano and Varignano; scholars have long pointed to these specific silhouettes as the likely inspiration for the backdrop of Sandro Botticelli’s 'The Birth of Venus'. The race concludes in the shadow of the same fortress that has guarded this bay since 1152, keeping the swimmer’s gaze fixed on a horizon defined by stone and salt.

A legend, a plaque and a cup

The swim Byron is said to have made across the gulf to visit Shelley probably never happened: the legend grew out of a plaque set into the rock of the Portovenere grotto in 1877, half a century after the poet's only, feverish stay at Lerici. The race that carries his name is real. Gio Batta Bibolini, engineer and president of the Lerici water polo club, created it in 1949; four editions were swum before a silence that lasted from 1955 to 1986. Today Lerici Sport runs it every August — 7.2 kilometres from Portovenere to the finish in front of the Hotel Shelley.
