MIAMI, FL — In a move that has sent shockwaves through the Formula 1 paddock, Sir Lewis Hamilton is set to announce a major change to his inner circle following the 2026 Miami Grand Prix, parting ways with his recently reunited trainer, Angela Cullen.
The partnership, which was famously re-established ahead of Hamilton’s 2025 move to Ferrari, appeared to be the key to his emotional and physical stability. However, reports suggest the duo have mutually decided to end their professional relationship for a second time, with the decision effective immediately after the American race.
Sources close to the Seven-Time World Champion indicate that the decision was made amicably, aiming to introduce “fresh energy” into his 2026 campaign. Hamilton is reportedly looking for a different, more specialized approach to his training routine as he adjusts to a new, intense technical partnership at Maranello.
Angela Cullen, who was described by Hamilton as a pivotal part of his “Project 44” support structure in 2025, will once again move on to new adventures outside the F1 spotlight, having previously worked in IndyCar after their first split in 2023.
The announcement, scheduled for the Monday following the Miami Grand Prix, will introduce a new performance trainer who has been shadowing Hamilton and Cullen during the opening races of 2026.
This restructuring comes during a challenging start to the season for Hamilton, who, despite experiencing his most intense winter training, struggled to secure podiums in the first few races of 2026.
Hamilton has been vocal about the need for change within his surroundings to “optimize teamwork,” highlighting that staying with the same patterns would not work, especially following a disappointing first year with Ferrari in 2025.
The change is seen as a crucial step for Hamilton as he strives to adapt to the 2026 car regulations and break a long streak without a victory.
Insiders suggest that the new trainer brings a background in cognitive performance, a shift from the holistic support Cullen provided.
While fans may be surprised by the change, those near Hamilton note that this is part of a broader “reset” initiated by the driver, who previously told fans “the time for change is now” in a New Year’s message.
The Miami Grand Prix will therefore be the final weekend for the iconic duo, closing another chapter in their long-shared history.
Hamilton will fly to Italy immediately after the race to finalize the transition, hoping that this new chapter finally brings the elusive eighth world title within reach.
