The weather forecast on the Hampshire coast has sounded the alarm, threatening to turn the 34th edition of the AJ Bell Great South Run into a battle of survival against the English Channel’s gusts. With winds expected to exceed 60 km/h this Sunday, the iconic stretch along Southsea Seafront—those final two kilometers fully exposed to the ocean—is shaping up to be an invisible wall capable of shattering any hopes for a PB over the 10-mile course.
The Wind Factor on Flat Tarmac
While Portsmouth boasts a pancake-flat profile with zero elevation gain, the lack of natural shelter transforms the race into a test of raw power and mental grit. Elite athletes, who typically target European record-shattering times on this certified 10-mile circuit, will have to ditch the stopwatch and focus on group tactics. Drafting will be crucial; tucking in behind other runners will make the difference between having legs for the final kick or bonking spectacularly before sighting Nelson’s Victory.
Saturday’s Opening Salvo
The action kicks off on October 17th with the AJ Bell Great South 5k, an explosive distance that will serve as a litmus test for the wind strength. In this short format, lactate threshold management takes a backseat to the ability to push through a headwind. Amateur runners aiming for a sub-20-minute mark will find the long straights of Clarence Esplanade their toughest technical challenge, forcing them to shorten their stride to maintain stability.
The Great Run organizers remain on high alert, with potential last-minute modifications to finish line structures if the storm intensifies. For distance running purists, this edition won’t be remembered for the 10k splits, but for the runners' ability to maintain race pace while salt spray and crosswinds try to blow them off the asphalt. The real story lies in the resilience of a city rallying behind its flagship race, even as the British weather serves up its harshest conditions.
